Re: [PATCH 2/2] dir: remove PATH_MAX limitation

'git status' segfaults if a directory is longer than PATH_MAX, because
processing .gitignore files in prep_exclude() writes past the end of a
PATH_MAX-bounded buffer.

Remove the limitation by using strbuf instead.

Note: this fix just 'abuses' strbuf as string allocator, len is always 0.
prep_exclude() can probably be simplified using more strbuf APIs.

FYI I had a similar patch [1] that attempted to lazily strbuf_init()
instead so that strbuf_ API could be used.
