Hello list,

As I shared on IRC, when `got import -I dir/` is used, `dir/` is *not*
ignored: fnmatch is called with the name in dirent's d_name, which
doesn't include a trailing slash if the entry is of type directory.
Do note that calling got_path_strip_trailing_slashes on `-I` argument
is not an option: 'dir*/' can have some nasty side effects. The patch
for regress/cmdline/import.sh below makes this explicit.

Same can be observed for .{cvs,git}ignore.

As for the fix, I believe it's outside of my reach for the time being.
The snippet below fixes it for import's case in a quite rough way: I
don't like malloc'ing on every iteration, but it seems the only way to
do it without screwing -portable (POSIX only mandates for d_name in
dirent, and doesn't specify a max size).

The best way to actually fix it should be as stsp@ suggested: unify the
ignore matching in both got import and the commands that deal with
.{cvs,git}ignore, and then fix the matching.
