[PATCH v4 00/12] Wildmatch v4

Really small updates. I did not want to resend it this soon but this may fix the compile errors for Junio. Changes are

 - cleanup in wildmatch.c so #include "cache.h" is at the top of the
   file.

 - wildmatch() returns no match if it encounters "**" without
   surrounding slashes. It returns a special code so we can actually
   show a warning at higher level. I don't want to do that now
   because I want to mark the pattern "broken" in attr.c/dir.c so
   the pattern will never be used again, and the message shown only
   once. That needs nd/attr-match-optim-more, but I don't want to tie
   this series to that just yet.
