Currently, revert_or_cherry_pick sets up a default git config, parses
command-line arguments, before preparing to pick commits. This makes
for a bad API as the central worry of callers is to assert whether or
not a conflict occured while cherry picking. The current API is like:
if (revert_or_cherry_pick(argc, argv, opts) < 0)
print "Something failed, we're not sure what"
Simplify and rename revert_or_cherry_pick to pick_commits so that it
only has the responsibility of setting up the revision walker and
picking commits in a loop. Transfer the remaining work to its
callers. Now, the API is simplified as:
if (parse_args(argc, argv, opts) < 0)
print "Can't parse arguments"
if (pick_commits(opts) < 0)
print "Error encountered in picking machinery"
Later in the series, pick_commits will also serve as the starting
point for continuing a cherry-pick or revert.
