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".
