Currently there are three completion functions that perform similar queries to 'git config' to get config variable names. These are the completion of aliases, remotes, and remote groups for 'git remote update'. Since the following patch is about to add yet another similar 'git config'-querying completion function to support pretty aliases, it's time to introduce a unified helper function first to avoid redundant code.
We took care that the resulting helper function still copes well with newlines in config variable values and that it works with 'set -u' (see commits e0d7805 (completion: fix alias listings with newlines, 2009-10-08) and 25a31f8 (bash-completion: Support running when set -u is enabled, 2009-01-15) for details).
