Previous change "maildir: hide invalid folders" prevents filepath.Walk
from descending into directories that don't contain new/, tmp/ or cur/
because the WalkDirFunc returns filepath.SkipDir.
We have to assume that these directories can be the parent of valid
maildir folders even if they're not themselves valid maildir folders, so
it is a mistake not to recurse into these subfolders. Fix it by
returning nil instead of filepath.SkipDir in the WalkDirFunc.

The Message-Id header cannot be relied upon as users can tweak it before
sending. The subject seems a more reliable basis to reorder patches.
Change the logic of sorting. Previously, all messages were required to
look like patches to be sorted. Now if at least one message looks like
a patch, all messages will be sorted by Subject before piping them.
Since `git am` ignores non-patch messages, it should allow piping series
of emails including reviews and comments without getting confusing
errors.
I have tested that this works on multiple series that appeared out of
order in my INBOX with the following command (after marking the
messages):
:pipe -m sed -n 's/^Subject: //p'

A little coding hygiene cannot hurt. Add a simple awk script to check
all source files for bad white space habits:
- trailing white space
- trailing new lines at the end of files
- missing new line at the end of files
- spaces followed by tabs
The script outputs color when the terminal supports it. It exits with
a non-zero code when there was at least one white space issue found.
Call the script in the lint step.
Example output of the awk script:
config/default_styleset:1:# <-- trailing whitespace
config/default_styleset:3:# <-- trailing whitespace
doc/aerc.1.scd:78: Executes an arbitrary command in the background. Aerc will set the <-- trailing whitespace
doc/aerc.1.scd:234: <-- trailing whitespace
doc/aerc.1.scd:237: <-- trailing whitespace
worker/types/thread_test.go:74: // return ErrSkipThread<-- space(s) followed by tab(s)
worker/lib/testdata/message/invalid/hexa: trailing new line(s)
Fix issues reported by the script.
NB: The ENDFILE match is a GNU extension. It will be ignored on BSD-awk
and trailing new lines will not be detected. The lint make target is
only invoked on alpine linux which has GNU awk anyway.
NB: Empty cells in scdoc tables require trailing white space... Avoid
this by setting content in these cells. I don't really see a use for
empty cells.

The MouseEvent method of the composer passes on the mouse event to it's

passes on the mouse event to child objects of the grid, which are
referenced via fields of the composer (c.editor is a field in composer
but a child of c.grid, for example). When the grid attempts to pass on
the mouse event, it is referencing a pointer which is locked, and a
deadlock occurs due to the original lock in composer.MouseEvent.

The vulnerability database is evolving with time. It can cause the lint
step to fail suddenly without any source code changes on our side.
Moreover, sometimes, there is nothing we can do to fix the issue nor to
silence that specific error.
Found 1 known vulnerability.
Vulnerability #1: GO-2022-1039
Programs which compile regular expressions from untrusted
sources may be vulnerable to memory exhaustion or denial of
service. The parsed regexp representation is linear in the size
of the input, but in some cases the constant factor can be as
high as 40,000, making relatively small regexps consume much
larger amounts of memory. After fix, each regexp being parsed is
limited to a 256 MB memory footprint. Regular expressions whose
representation would use more space than that are rejected.
Normal use of regular expressions is unaffected.
Call stacks in your code:
config/config.go:1000:46:
git.sr.ht/~rjarry/aerc/config.AercConfig.LoadBinds calls
regexp.Compile, which eventually calls regexp/syntax.Parse

The Invalidatable struct is designed so that a widget can have a
callback function ran when it is Invalidated. This is used to cascade up
the widget tree, marking things as Invalid along the way so that only
Invalid widgets are drawn. However, this is only implemented at the grid
cell level for checks if the cell is invalidated -- and the grid cells
are never set back to a "valid" state. The effect of this is that no
matter what is invalidated, the entire UI gets drawn again.
The calling through the Invalidate callbacks creates *several* race
conditions, as Invalidate is called from several different goroutines,
and many widgets call invalidate on their parent or children.
Tcell has optimizations to only rerender screen cells that have changed
their rune and style. The only performance penalty by redrawing the
entire screen for aerc is the operations *within the aerc draw methods*.
Most of these are not expensive and have relatively no impact on
performance.
Skip all of the OnInvalidates, and directly invalidate the UI when
DoInvalidate is called by a widget. This reduces data races, and
simplifies the widget redraw logic signficantly.

The terminal widget uses it's own redraw logic to improve performance.
With the addition of a main event loop, the redraw logic can happen in
the main loop via the standard Invalidate logic.
Use the Invalidate method to mark aerc invalid, and immediately trigger
a redraw with ui.QueueRedraw. The follow up call to QueueRedraw is
needed because the terminal update happens in a separate goroutine. This
can result in the main event loop finishing it's process of the current
event, redrawing the screen, and the terminal having additional updates
to be drawn.
This fixes race conditions by drawing and calling screen.Show in a
separate goroutine.
