```
I accidentally created a branch whose name starts with  "+".
Everything went ok until I pushed it  because "+" is interpreted as
forced refspec (e.g. "git push somewhere +wip"). Using full ref names
would avoid ambiguity. The corner case of this is where the branch
name is simply "+". Then refspec "+:" will be interpreted completely
different from what the user wants. I wonder if we could do something
better:

 - forbid "/+" in ref names (too strong?)
 - some heuristics to detect "+:" and refuse it if ref "+" exists.
heuristics to hint the user about full ref name after we fail to match
refspec because we misinterpret "+"
 - improve refspec matching code to detect ambiguation and force using
full ref name.

Using full ref names does not avoid ambiguity in that case?  What
is a push refspec with an empty right-hand-side supposed to do in
the first place anyway?
