From: Han-Wen Nienhuys <hanwen@xxxxxxxxxx> A grep for EINVAL */*c reveals that no code inspects EINVAL after reading references. The files ref backend does use EINVAL so parse_loose_ref_contents() can communicate to lock_raw_ref() about garbage following the hex SHA1, or a short read in files_read_raw_ref(), but the files backend does not call into refs_read_raw_ref(), so its EINVAL sideband error is unused. As the errno sideband is unintuitive and error-prone, remove EINVAL value, as a step towards getting rid of the errno sideband altogether. Spotted by Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx>.
