Sidebar closes after save and delete

[David Woodfall]

I've noticed since I've been using the sidebar that it closes when
deleting or saving a message in index and pager.

I managed to fix the delete problem by changing the macro to:

s=Trash<enter>":set sidebar_visible<enter>"

But this doesn't work with <save-message> for some reason. It looks
like something is closing it after my macro has finished.

Any ideas?
