This commit changes the rules for resolving refspecs to match the rules for resolving refs in rev-parse. git-rev-parse uses clear rules to resolve a short ref to its full name, which are well documented. The rules for resolving refspecs documented in git-send-pack were less strict and harder to understand. This commit replaces them by the rules of git-rev-parse.
The unified rules are easier to understand and better resolve ambiguous cases. You can now push from a repository containing several branches ending on the same short name.
Note, this breaks existing setups. For example "master" will no longer resolve to "origin/master".
