A few bits about the RCS backends

## Terminology
It follows that the HTML rendering and the CGI handling can be completely
separated parts in ikiwiki.

#### Rationale for doing it differently than in the Subversion case

## [[Git]]
Regarding the Git support, Recai says:
> it seems to me you could just git-stash them now that git-stash exists.

By design, Git backend uses a "master-clone" repository pair approach in contrast
to the single repository approach (here, _clone_ may be considered as the working
copy of a fictious web user). Even though a single repository implementation is
command to save disk space.
Note that, as a rule of thumb, you should always put the rcs wrapper (`post-update`)
-into the master repository (`.git/hooks/`) as can be noticed in the Git wrappers of
-the sample [[ikiwiki.setup]].
+into the master repository (`.git/hooks/`).
Here is how a web edit works with ikiwiki and git:
revision with conflict markers to the repository. It then returns the text to the
user for cleanup. This is less neat than it could be, in that a conflict marked
revision gets committed to the repository.
