Ah, no, I misread what you meant.
Yes, historically when matching a path with a pattern "a/b[c-d]/e",
we tried to first literally match the path with it (this allows the
path "a/b[c-d]/e" to match with the pattern), and if it did not
match, used fnmatch(3) to allow "a/bc/e" to also match. This was an
ugly hack to cope with the possiblity that such a funny path is
actually used in projects.
With :(literal) magic and its friends you are working into the
system, the hack should disappear at the same time when you stop
running fnmatch(3) without FNM_PATHNAME. That should happen no
later than Git 2.0.
But until then, we should keep matching both paths "a/bc/e" and
"a/b[c-d]/e" with pattern "a/b[c-d]/e", for backward compatibility.
Sorry about the earlier confusion.
