Send an email to 2676-done@emacsbugs.donarmstrong.com and it will be
closed.
For doing more than that see emacs/admin/notes/bugtracker

I take responsibility for the error thrown by `vc-dir-deduce-fileset'.
How about saying something like:

VC operations when applied to multiple files require files to be in
similar VC states.
%s in state %s clashes with %s in state %s

If you have suggestions for this and other messages, they shouldn't be
too hard to improve.

In general some facility that shows tips for various modes would be
useful to have in emacs.
