This is primarily due to the fact that we can't make as many assumptions on the kind of data that is fed to "git grep." So, limit when UTF mode can be enabled by introducing "is_log" to struct grep_opt, checking to see if it's a non-zero value in compile_pcre2_pattern() and only mutating it in cmd_log() so that we know "git log" was invoked if it's set to a non-zero value.
