Merge branch 'ab/push-dwim-dst'

"git push $there $src:$dst" rejects when $dst is not a fully
qualified refname and not clear what the end user meant.  The
codepath has been taught to give a clearer error message, and also
guess where the push should go by taking the type of the pushed
object into account (e.g. a tag object would want to go under
refs/tags/).

* ab/push-dwim-dst:
push doc: document the DWYM behavior pushing to unqualified <dst>
push: test that <src> doesn't DWYM if <dst> is unqualified
push: add an advice on unqualified <dst> push
push: move unqualified refname error into a function
push: improve the error shown on unqualified <dst> push
i18n: remote.c: mark error(...) messages for translation
remote.c: add braces in anticipation of a follow-up change
