Re: BUG: git clean -d cannot remove files from read-only directories

Adam Milazzo [off-list ref] writes:

Repro steps:
1. git init 
2. mkdir d
3. touch d/a
4. chmod -w d
5. git clean -fd

Actual result:
Git doesn't remove anything, saying "warning: failed to remove d/a".

Expected result:
Git should remove the subdirectory 'd' along with its
contents. Note that git can remove a read-only file (touch b;
chmod -w b; git clean -f) with no problem.

It is how UNIX-like filesystem works, isn't it?

As long as a directory D is writable/executable, any regular file
inside it can be removed regardless of the perm-bits of the file.

	mkdir d
	touch d/a
	chmod -w d
	rm d/a

would not let you remove the file d/a from d/, exactly because you
cannot modify d/ (it is not writable).
