[PATCH 0/2] git-config and large integers

I was playing with a hook for file size limits that wanted to store the limit in git-config. It turns out we don't do a very good job of big integers:

  $ git config foo.size 2g
  $ git config --int foo.size
  -2147483648

Oops. After this series, we properly notice the error:

  $ git config --int foo.size
  fatal: bad config value for 'foo.size' in .git/config

and even better, provide a way to access large values:

  $ git config --ulong foo.size
  2147483648

The patches are:

  [1/2]: config: properly range-check integer values
  [2/2]: teach git-config to output large integers
