Would it be crazy for grep --exclude-dir=foo/bar to give a warning?
Since, as I understand it, any non-trailing / in the arg can never match
since the arg is matched against the basename.
That's not quite true, as it can match command-line arguments. For example:
$ grep -rl . lib/* | grep '^lib/unictype/\.gitignore$'
lib/unictype/.gitignore
$ grep --exclude-dir=lib/unictype -rl . lib/* | grep
'^lib/unictype/\.gitignore$'
$
It should be possible to give useful warnings in some cases, though.
It's too bad the rules are so complicated - that's partly my fault, as
the various options were added at different times and I didn't think
things through as suggestions were made. Probably too late to change the
meaning of existing options now, though.
