Could you please try the patch below, and see if it avoids the "lax"
matches and the confusing effect of deleting "a" in the scenario above
is avoided on OS X?
(This is not the full patch, since we need to add this code only for
some file-name encodings, such as utf-8-hfs. If this works for you, I
will add the missing bits. If it doesn't work, please tell where I
goofed.)
Thanks.
