Hi Andreas,

Manpage of grep, exit staus:

   "Normally, the exit status is 0 if selected lines are found and 1
otherwise. But the exit status is 2 if an error occurred, ..."

cmp uses the same convention (albeit not reported in its manpage).

I am not stating that all linux commands and utilities follow exactly
the same convention, but these
two are at least consistent with themselves always returning an exit
status that has a well defined meaning. git-config returns
consistently the exit status, it only issues in certain cases messages
and in others not. A consistent solution could be for it to return 0
upon success, 1 when the section or key is absent, and 2 when the
config file does not exist or is corrupt issuing also an error
