[PATCH 09/10] pickaxe: call strlen only when necessary in diffcore_pickaxe_count()

["René Scharfe" <l.s.r@web.de>]

We need to determine the search term's length only when fixed-string
matching is used; regular expression compilation takes a NUL-terminated
string directly.  Only call strlen() in the former case.
