[TxMt] Monaco 12 pt italicized quotes display problem

[Ed Allen]

I'm a Textmate n00b, so maybe there is just something I have  
misconfigured, but just in case it is a bug...

I noticed today that I wasn't seeing quotes correctly in comments at  
my default settings. My default font is Monaco 12 pt. Anti-aliasing  
is off. Inside of comments which are italicized, I noticed that I  
don't see single quotes at all (just a space) and double quotes as  
single quotes. This problem doesn't happen in the non-italicized code  
text and goes away in italicized text if I boost the text size to 14  
pt. It also goes away if I turn off the italics styling on comments.

So is there something I need to tweak to get quotes looking right in  
the italicized text?

I checked TextEdit for comparison with antialiasing turned off in the  
System Preferences for 12 pt and lower, and the quotes in Monaco are  
normal there.
