Currently if we have a config file like, [foo] baz bar = and we try something like, "git config --add foo.baz roll", Git will segfault. Moreover, for "git config --add foo.bar roll", it will overwrite the original value instead of appending after the existing empty value. The problem lies with the regexp used for simulating --add in `git_config_set_multivar_in_file()`, "^$", which in ideal case should not match with any string but is true for empty strings. Instead use a regexp like "a^" which can not be true for any string, empty or not. For removing the segfault add a check for NULL values in `matches()` in config.c.
