special-display-buffer-names and vc-diff displays wrong result |

Symptoms:
I am using `special-display-buffer-names' for the *vc-diff* buffer.
If the special-display-buffer frame does not exist then the *vc-diff*
buffer reports sometimes "No differences found.". This seems to due
the fact that the 'vc-diff-internal' function has not written yet any
bytes into the *vc-diff* buffer. The strange part is that this only
happens if the background process ends up very fast. For example a
diff with the cvs.gnu.org server finishes always successfully, but a
diff with the local cvs server fails.
I don't know how to fix this. As a workaround I put after the
vc-diff-internal function a (sit-for 1) statement. Then it seems to
work.
