Just add another pack command rather than extending this one.

This is hard to read because the continuation line isn't indented
further that the first line.  Please indent continuation lines by an
extra 4 spaces.

"string is integer" will already accept the null string and return 1.

Once again, "string is integer" returning 1 doesn't guarantee the
string is non-empty.  Use "string is integer -strict" if you want
that.

Inconsistent indentation.

It would be nice to save diffcontext in the ~/.gitkrc.
