Subject: Parameter expansion, patterns and fnmatch

Hello,
I'm seeing some discrepancies between dash built with --enable-fnmatch
and dash built without that got me curious. Maybe you could help shed
some light?
foo='[abc]'
echo ${foo#[}
echo ${foo#\[}
With dash built with --enable-fnmatch:
abc]
abc]
With dash built without --enable-fnmatch:
[abc]
abc]
I was able to reproduce this behavior on latest git master
(17a5f24e0). The dash manual states:
> The end of the character class is indicated by a ]; if the ] is
> missing then the [ matches a [ rather than introducing a character
> class.
Which to me suggests that the non-fnmatch case is not the expected
behavior. Is this interpretation correct?
Thanks,
