"git pack-objects" has the option --max-pack-size to limit the file size of the packs to a certain amount of bytes. On platforms where the pack file size is limited by filesystem constraints, it is easy to forget this option, and this option does not exist for "git gc" to begin with.
So introduce a config variable to set the default maximum, but make this overrideable by the command line.
Suggested by Tor Arvid Lund.
