cvs-mode-diff on marked files

[Juri Linkov]

I wonder what are the reasons for cvs-mode-diff to ignore selected
files?  It is very convenient to mark all relevant files in the *cvs*
buffer and type `=' to generate a composite patch.  But currently
`cvs-invert-ignore-marks' contains "diff" by default, thus preventing
`=' to operate on all selected files.  It operates only on the current
file at point.  Even the documentation string of `cvs-mode-diff' says
"Diff the selected files against the repository" where "selected files"
is in the plural form.
