Evergreen comment highlighting confused by Ruby's #{} (1721/3258/1.6.0_13-b03/Linux 2.6.35.13-weta-20110808/amd64 x2)

As in the attached image, Evergreen needs to distinguish between use of # to begin comments and use of #{} substitutions:

without really parsing Ruby, i wonder how well you can fix this. in
the screenshot you provide, iirc, the only reason we get the first #{}
right is that there's no space before the #. so if you wanted to
hard-code a belief that #{ is never a comment (even though, in theory,
it could be), there'd be no moral high ground for any opponent of such
a hack to take. (short of proffering a real Ruby parser.)
