Why?

Instead of using a static global variable, perhaps make this an
on-stack variable in load_commands_and_aliases() that is passed as a
callback parameter to load_aliases_cb() thru git_config()?

That is, cb here is the second parameter you gave to git_config().

This will not break the use of "git help -a" in our completion
script, because it ignores anything that does not begin with two SP
followed by alphanumerics.
It may however break scripts that read from "help -a" done by other
people that may remove the lines in the output that are known to
them as not names of commands (i.e. "available git commands..." and
"git commands avaliable elsewhere...")---they haven't seen this new
string and would not know that this line must be skipped.
Other than that, looks reasonably cleanly done. We'd need a test to
cover this so that other people will not break it in future patches.
