Oh,
Charles, my English must be failing me tonight.
Yes, yes!
Does it mean
"Yes, it does. It does need a colon within this context!"
or
"No, it doesn't. It does not need a colon within this context!"
The reason why I'm asking is because the Russian sentences like "No, it does" and "Yes, it doesn't" are perfectly legal and only correct from the Russian grammar perspective.
Sorry for being especially dumb tonight.
P.S. Can be confusing when one quote mark is missing
Should have proper syntax highlighting in your editor to avoid confusion.
