http-push: trim trailing newline from remote symrefjk/http-push-symref-fix
When we fetch a symbolic ref file from the remote, we get the whole string "ref: refs/heads/master\n", recognize it by skipping past the "ref: ", and store the rest. We should chomp the trailing newline. This bug was introduced in ae021d8 (use skip_prefix to avoid magic numbers, 2014-06-18), which did not notice that the length computation fed to xmemdupz was quietly tweaked by 1 to account for this. We can solve it by explicitly trimming the newline, which is more obvious. Note that we use strbuf_rtrim here, which will actually cut off any trailing whitespace, not just a single newline. This is a good thing, though, as it makes our parsing more liberal (and spaces are not valid in refnames anyway). Signed-off-by: Jeff King <peff@peff.net> Tested-by: Kyle J.
