[PATCH] Detect misspelled pathspec to git-add

[Junio C Hamano <junkio@cox.net>]

This is in the same spirit as an earlier patch for git-commit.
It does an extra ls-files to avoid complaining when a fully
tracked directory name is given on the command line (otherwise
--others restriction would say the pathspec does not match).

 * I noticed this when I accidentally said "git add /a/b/c"
   when I meant "git add a/b/c", and I did not notice it until
   I said "git commit" which said "Nothing to commit."

   It does one extra ls-files only if any pathspec is given; I
   am hoping this slight performance hit is tolerated.  I think
   people who does "git add ." all the time to mean "add
   everything I added anywhere since I did git add last time"
   deserve it ;-).
