My guess is that this was done as a usability fix for those cases when 
you DON'T want the abbreviation. That's not likely with Ctrl+Enter but 
is likely with space.

Let's say you wanted to type the phrase "we're " in a comment. Since "re 
" is an abbreviation for "return" you end up with "we'return ". Now you 
go back and delete it to "we're" and hit space to continue - if it 
always expanded this would become "we'return" again!

So I'm guessing the abbreviations code is only doing abbreviation 
expansion if you type the abbreviation correctly - if you edit around it 
it doesn't.

(This is just speculation but I don't want it to start expanding always 
for the case when space is used as the expand key)
