AFAIK, `enlarge-window' did not signal an error when the size was too
large, so I think it's best to keep being silent, for backward
compatibility's sake.

Signalling an error is a good thing, wo while we shouldn't do it for
enlarge-window for compatibility reasons, we should do it for the
new functions like window-resize.

Such changes to interactive behavior are much less problematic than
changes in non-interactive functions, since the first might at worst
surprise or disappoint the user, while the second can
break functionality.
