SZEDER Gábor[PATCH 1/2] completion: add a helper function to get config variables
Currently there are a few completion functions that perform similar 'git config' queries and filtering to get config variable names: the completion of pretty aliases, aliases, and remote groups for 'git remote update'.
Unify those 'git config' queries in a helper function to eliminate code duplication.
Though the helper functions to get pretty aliases and alieses are reduced to mere one-liner wrappers around the newly added function, keep these helpers still, because users' completion functions out there might depend on them. And they keep their callers a tad easier to read, too.
Add tests for the pretty alias and alias helper to show that they work as before; not for the remote groups query, though, because that's not extracted into a helper function and it's not worth the effort to do so for a sole callsite.
