There's another case where this goes wrong, that isn't fixed by your, my, or Herbert's patches:

$ dash -c 'a=\\a; echo "${a#\*}"'

$ bash -c 'a=\\a; echo "${a#\*}"'

My patch and Herbert's preserve dash's current behaviour, your patch makes it print a. None of that is correct, the result should be the same as bash.

Never mind, this is a very bad test. I forgot about echo's backslash handling. Had my terminal emulator given any feedback on \a, I might have noticed that before sending. This test doesn't show anything wrong in this area, but I'll check a bit more.
