Correction to vistartup program

[Dolf Starreveld]

There was a bug in the vi startup program I posted to the net a week
ago. It caused the program to behave incorrectly when it was called
with option arguments as in:

	vi +100 junk.c

I corrected the bug and a diff-listing follows.
Also I changed to program not to stop with a fatal error condition
if the format of the ".virc" file is incorrect. Now the incorrect line
is skipped with a warning.
