xrevbump: various improvements

- commit all tracked files in srcpkgs/$pkgname/ instead of just template
- don't increment revision if the user has already done it
    - this also handles cases where committing fails, which now prints a
      message (two failure modes I have encountered: commit signing
      fails, pre-commit hook fails (I run `xlint` in one))
- allow addition of flags to the `git commit` invocation with
  `xrevbump MESSAGE TEMPLATES... -- COMMIT_ARGS`
- use more bashisms to make things a bit neater
- update manpage/usage
