builtin/fetch.c: ignore merge config when not fetching from branch's remote
When 'git fetch' is supplied a single argument, it tries to match it against a configured remote and then fetch the refs specified by the named remote's fetchspec. Additionally, or alternatively, if the current branch has a merge ref configured, and if the name of the remote supplied to fetch matches the one in the branch's configuration, then git also adds the merge ref to the list of refs to update. If the argument to fetch does not specify a named remote, or if the name supplied does not match the remote configured for the current branch, then the current branch's merge configuration should not be considered. git currently mishandles the case when the argument to fetch specifies a GIT URL(i.e. not a named remote) and the current branch has a configured merge ref. In this case, fetch should ignore the branch's merge ref and attempt to fetch from the remote repository's HEAD branch. But, since fetch only checks _whether_ the current branch has a merge ref configured, and does _not_ check whether the branch's configured remote matches the command line argument (until later), it will mistakenly enter the wrong branch of an 'if' statement and will not fall back to fetch the HEAD branch. The fetch ends up doing nothing and returns with a successful zero status. Fix this by comparing the remote repository's name to the branch's remote name, in addition to whether it has a configured merge ref, sooner, so that fetch can correctly decide whether the branch's configuration is interesting or not, and fall back to fetching from the remote's HEAD branch when appropriate. This fixes the test in t5510. Signed-off-by: Brandon Casey <casey@nrlssc.navy.mil> Signed-off-by: Junio C Hamano <gitster@pobox.com>
