Massive thanks to durka on #lisp on irc.freenode.net.
New versions of slime for emacs have had enabled by default a new feature, essentially a light highlighting of uncompiled changes to a file. At first I found it annoying but then I got used to it. It is kind of handy. However I wouldn't find out how to turn it on or off. Oh well.
Then I went to use emacs on the console and the subtle light grey background highlight was suddenly grey text on a white background and completely unreadable. Very annoying, suddenly this little feature rendered -nox emacs useless.
Hours of google searching turned up nothing so finally I resorted to the irc channel. In only 10 minutes we got the answer.
<durka> aha customize emacs - applications - slime - slime mode - slime mode faces change highlight edits face
Thank you.

What does “highlighting of compiled changes to a file” mean? Sounds interesting.

ha, a typo… I think I blindly let Firefox’s spell checker changed unrecognized ‘uncompiled’ to a recognized ‘compiled’
It is highlighting of uncompiled changes to a file. My bad, and fixed. Thanks for noticing.
Basically it’s cool because you can end up with lots of uncompiled code in a file as Slime/Emacs lets you compile single functions in a file so it’s just a nice visual reminder of what’s been compiled and what hasn’t when you go to test stuff.

Oh, I see. That sounds very useful. I need to grab a new slime off of CVS.

It took a bit of time to get used to at first. But now I kind of like it. Except the console colors need tweaking because right now they are useless.
