If you read (and you should :-)
you will see the reason for the "syntax checking".
We currently need manual white listing (of e-mail addresses),
because we had months of "spam" bug reports and then complete
spam explosion aka "bug site devastation" action.
I have added your e-mail (above) to be valid / legal...
Please "subscribe", because we will not keep that changed string for so long.
[ Actually, I'd tend to say that for short term, we are now
looking for volunteers for "bugzilla moderation".... ]

as a workaround, yes, thank you David!

Still, I would tend to think that it was reasonable feature
request to ask for plot.ts() to be improved there, and then
R-devel or the R-bugzilla would be ok, too.
