[PATCH v3 2/2] search: Support automatic tag exclusions

Austin Clements amdragon at MIT.EDU
Sat Jan 14 16:17:34 PST 2012


This adds a "search" section to the config file and an
"auto_tag_exclusions" setting in that section.  The search and count
commands pass tag tags from the configuration to the library.
