parentrefs: parse_hide_refs_config to use parse_config_key (diff)

parse_config_key: use skip_prefix instead of starts_with
This saves us having to repeatedly add in "section_len" (and also avoids walking over the first part of the string multiple times for a strlen() and strrchr()). Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
