Subject: [PATCH] Add config_int() method to the Git perl module

Integer variables can have optional 'k', 'm' or 'g' suffix.
config_int() method will return simple decimal number, taking
care of those suffixes.

+Retrieve the integer configuration C<VARIABLE>. The return value
+is simple decimal number.  An optional value suffix of 'k', 'm',
+or 'g' in the config file will cause the value to be multiplied
+by 1024, 1048576 (1024^2), or 1073741824 (1024^3) prior to output.
+It would return C<undef> if configuration variable is not defined,
+
+Must be called on a repository instance.
+
+This currently wraps command('config') so it is not so fast.
