pacdiff: rework search type handling, add --find option
Change cmd tests to if (( USE_FIND ))... as it is cleaner. All search cmds have an option and a variable initialized to zero. The active option should be set to 1. Add a switch to exclude multiple search options. set the default when all are equal to zero. Signed-off-by: Jonathan Frazier <eyeswide@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
