This would need some clean-up indeed or maybe better documentation.
They might be a bit difficult and I have to look at the code from time
to time. However, I found some these policies useful. For example, I
just do a "stg pull" from a Subversion repository with the config
below:

[stgit]
        pull-policy = fetch-rebase
        fetchcmd = git svn fetch
        rebasecmd = git svn rebase

I still find "rebase" useful and use it in some situations when I
don't need a pull. As Jakub mentioned, maybe we could keep the
"rebase" functionality outside of the "pull" command (make it part of
Stack with a corresponding Branch.rebase?) and have "rebase" use it.

OK.

But "pull" always suggests fetching something. Adding "--rebase" would
mean that it doesn't fetch. Shouldn't we leave this functionality to
"rebase" only?

These are OK, with the comment on have rebase functionality in "rebase" only.

OK.

I don't use it either but there might be people that have complicated
configurations and they mix Git commits with StGIT patches. Not sure
though.
