confusing messages

[Sam Steingold]

I see these messages:

$ bzr pull
Using saved location: http://bzr.xsteve.at/dvc/
0 revision(s) pulled.
$ bzr update
Tree is up to date at revision 136.
$ bzr status
pending merges:

$ bzr merge
Merging from remembered location http://bzr.xsteve.at/dvc/
Nothing to do.
$ bzr status

so, why do I see "pending merges" if merge says "Nothing to do"?

Thanks.
Sam.

PS. in case it matters: I have been using CVS for many years, RCS before 
it. Alas, I am forced to use baz and bzr now...
