When calling "vim-patch.sh -s" on a checked-out branch created with
"vim-patch.sh -p", create commit from staged changes, push to origin,
create pull request (using hub), and clean up patch files.
Any patch may contain mixed encodings, so we must process them as byte
arrays. E.g. with stock `sed` on OS X patch
8a94d873aa8c753a8522ea86a049bdf2abd0c507 causes this error:
sed: RE error: illegal byte sequence
To avoid that, set LC_ALL=C.
Also remove redundant *.patch creation from review_pr().
* Link to the commit details on GitHub for a tagged version.
* Non-tagged patches (runtime updates) are still linked to
Google Code because they are identified by a Mercurial commit hash.
- Check for mercurial before using it
- Make 'Merging patches...' wiki page easier to copy
- Use `basename` instead of assuming the user is running vim-patch.sh
via the repo root
- Appease shellcheck by quoting path variables
- Remove unneeded variable quoting inside [[ ]] blocks
- Don't unconditionally 'exit 1'
'-h' and '--help' are both recognized options, so current behavior is
misleading.
