Recording merges after repo conversion

Hi!

I have a couple of repositories converted from CVS to Git using
parsecvs. Some are just converted, some I've continued to develop after
the conversion (and cloned a couple of times).

Since parsecvs gave me all the CVS branches, I would like to record the
merge points in the Git history, if possible. I have commited merges
with comments like "merged <branchname>", so I can probably find them
quite easily, and I do have the imported CVS branches available. Can I
record the merge information so git knows about them?

Is it safe to do so on a repository that has already been cloned (i.e,
will a later push/pull work)?
