Currently:

This is what I expect, and also what bash, ksh and posh do.
With your patch:
$ dash -c 'foo=a; echo "<${foo#[a\]]}>"'
<a>
Does the attached look right as an alternative? It treats a quoted
backslash the same way as if it were preceded by CTLESC in _rmescapes.
It passes your test case and mine, but I'll do more extensive testing.
It causes preglob's string to potentially grow larger than the original.
When called with RMESCAPE_ALLOC, that can be handled by increasing the
buffer size, but preglob also gets called without RMESCAPE_ALLOC to
modify a string in-place. That's never going to work with this approach.
Back to the drawing board...
