Produces a raw patch for a single commit (diffed against its first
parent), or a patch-series for a revspec of 2 commits (e.g.
3a8b42..9ff173 where the first commit represents the source and the
second commit the destination).
In case of the latter (diffing a revspec), a patch series is returned
for the commits on the source branch (3a8b42 and its ancestors in
our example).
While similar to diffs, patches:
- Have a commit header (username, commit message, etc)
- Do not support the
path=foo/bar.pyquery parameter
The raw patch is returned as-is, in whatever encoding the files in the
repository use. It is not decoded into unicode. As such, the
content-type is text/plain.
