[PATCH 0/3] ld/push-porcelain

Changes since last version:

* removed git-push: squelch advice message if in --porcelain mode
* chaned "error message" to "advice message" in commit subject

Larry D'Anna (3):
  git-push: fix an advice message so it goes to stderr
  git-push: send "To <remoteurl>" messages to the standard output in
    --porcelain mode
  git-push: make git push --dry-run --porcelain exit with status 0 even
    if updates will be rejected

These sort of messages typically go to the standard error.

The script calling git push --dry-run --porcelain can see clearly from the
output that the updates will be rejected.  However, it will probably need to
distinguish this condition from the push failing for other reasons, such as the
remote not being reachable.

1.7.0.rc2.40.g7d8aa

git-push prints the line "To <remoteurl>" before above each of the ref status
lines.  In --porcelain mode, these "To <remoteurl>" lines go to the standard
error, but the ref status lines go to the standard output.  This makes it
difficult for the process reading standard output to know which ref status lines
correspond to which remote.  This patch sends the "To <remoteurl>" lines to the
the standard output instead.

I thought that in the previous iteration, the status won't be touched
anymore? You agreed too:
