revision: provide implementation for diff merges tweaks

Browse Source 
Use these implementations from show_setup_revisions_tweak() and
log_setup_revisions_tweak() in builtin/log.c.

This completes moving of management of diff merges parameters to a
single place, where we can finally observe them simultaneously.
