Thanks. I see you changed
color brightgreen "([\"']).*?[^\\]\1"
to
color brightgreen "(["']).*[^\\]\1"

which seems to work fine, even though it ends up not quite
nanorc syntax highlighted (highlit? :) in my .nanorc.

That triple-quote line:
color brightgreen start="("""|''')" end="("""|''')"
doesn't work though.

When I type ''' or """ in my Python code, everything in the file
before that triple-quote (up to the top of the buffer) gets syntax
highlighted to that one solid color of brightgreen.

Thanks,
