[PATCH 0/4] attribute regression fix for maint-1.8.1 and upward

So here is an attempt to fix the unintended regression, on top of
9db9eecfe5c2 (attr: avoid calling find_basename() twice per path,
2013-01-16).  It consists of four patches.

The first patch is not essential to the fix, but I think it
clarifies what is going on in this codepath.

The second patch addresses the issue Jeff noticed; it appears as if
match_basename() takes counted strings, but one of the strings was
not a counted string at all.  Its length was given to the function
because the caller already had one, so that we do not have to do
strlen() ourselves.  And the other one was meant to be a counted
string, but the callee was not using it as such.  The patch makes
them both counted strings and treat them as such.

The third patch is the main fix.  As I said in the log message, I
didn't look at it very carefully, so extra sets of eyeballs are very
much appreciated.

The last one is a test stolen from Jeff to seal the series.  It
needs sign-off from Jeff.

Jeff King (1):
  make sure a pattern without trailing slash matches a directory

Junio C Hamano (3):
  attr.c::path_matches(): the basename is part of the pathname
  dir.c::match_basename(): pay attention to the length of string
    parameters
  attr.c::path_matches(): special case paths that end with a slash
