I'm in the camp of these (counter) arguments.

When my shell script asks for 'git config --int 3g', I expect to be
returned a positive 10-digit. What would I care which type Git or any
other tool is using internally? I only care whether my shell can work with
numbers that large. Or the next tool that I feed the number to. But that's
my business, not Git's.

And it better stays that way. Magic numbers should be encoded with magic
strings in the config file.
