Yes, a good hint and objection - but for these cases a call to
vc-recompute-state should fail with an error (e.g. because the
executable "cvs.exe" under Windows can n ot be found and therefore
the process-call "cvs status" fails.... and my program calls these
"check-state-function" with ignore-errors so the call returns in fact
nil for my program which indicates an unkown state and is displayed with
a ?-icon. What do you think - is this a satisfying approach?
