Don't use Boyer-Moore if repeated octets & case-insensitive search. 2010-01-30 Aidan Kehoe <kehoea@parhasard.net> * search.c (search_buffer): Don't use Boyer-Moore for case-insensitive search if the search pattern contains repeated Ibytes and the corresponding character has case information (or, equivalently, if one of its case equivalents would contain repeated Ibytes).
