Since we encourage using variables rather than magic hashes in the commit
fields, e.g. (commit version) and (commit commit), the default for
tempel to use quoted strings is rather off. Thus, let the placeholder reflect
actual usage.
* etc/snippets/tempel/scheme-mode (git-reference...)[commit]: Use field name
as placeholder and don't quote value.
(svn-reference..., bzr-reference...)[revision]: Likewise.
(hg-reference...)[changeset]: Likewise.
