Hrm, I took a look at this and I'm a bit stumped.

I think the logic in builtin-clean is a bit suspect, and I have a patch
below that fixes it.

However, I still can't get something as simple as:

  mkdir dir.clean &&
  touch dir.clean/file &&
  git clean -d "*.clean/"

to work, and I think the pathspec matching is to blame. If I use
"*.clean/", then read_directory assumes that "*.clean" is a directory to
be opened, without considering that it might be a wildcard, which is
just wrong. If I use "*.clean", then I get the correct directory
listing, but match_pathspec fails because read_directory returns
"dir.clean/". We could fix this by passing match_pathspec ent->len - 1,
but that actually ends up getting ignored! It ends up handing the string
to fnmatch, which treats it like a C string.

Am I crazy, or do we need to fix the wildcard semantics for directories
with both read_directory and with match_pathspec?

Below is my partial patch for reference.
