Giving "--invert-grep" and "--all-match" without "--grep" to the "git log" command resulted in an attempt to access grep pattern expression structure that has not been allocated, which has been corrected. * ab/grep-simplify-extended-expression: grep.c: remove "extended" in favor of "pattern_expression", fix segfault
