use skip_prefix to avoid repeating strings
It's a common idiom to match a prefix and then skip past it with strlen, like: if (starts_with(foo, "bar")) foo += strlen("bar"); This avoids magic numbers, but means we have to repeat the string (and there is no compiler check that we didn't make a typo in one of the strings). We can use skip_prefix to handle this case without repeating ourselves. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
