Subject: send-pack: reword non-fast-forward error message.
X-Git-Tag: v1.0.3^2~3
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=69310a34cb6dcca32b08cf3ea9e91ab19354a874;p=git.git

send-pack: reword non-fast-forward error message.

Wnen refusing to push a head, we said cryptic "remote 'branch'
object X does not exist on local" or "remote ref 'branch' is not
a strict subset of local ref 'branch'".  That was gittish.

Since the most likely reason this happens is because the pushed
head was not up-to-date, clarify the error message to say that
straight, and suggest pulling first.

First noticed by Johannes and seconded by Andreas.
