There are four wildcard characters in p4. Files with these characters can be added to p4 repos using the "-f" option. They are stored in %xx notation, and when checked out, p4 converts them back to normal. When adding files with wildcards in git, the submit path must be careful to use the encoded names in some places, and it must use "-f" to add them. All other p4 commands that operate on the client directory expect encoded filenames as arguments. Support for wildcards in the clone/sync path was added in084f630(git-p4: decode p4 wildcard characters, 2011-02-19), but that change did not handle the submit path. There was a problem with wildcards in the sync path too. Commit084f630(git-p4: decode p4 wildcard characters, 2011-02-19) handled files with p4 wildcards that were added or modified in p4. Do this for deleted files, and also in branch detection checks, too.
