     What terminates a comment inside such a block?

     Is the "lolcat1," part of the comment about kittens?

     Is the "\" part of the comment?  The early comment line about
kittens lacks a "\".  Are both validly continued lines?

     Wow.  That's the most incredibly *ugly* kluge I've seen in many a year,
but if it works, then at least it does provide the functionality.  I'll
make the required changes to a copy of torrc and then try the upgrade to
0.2.2.17-alpha sometime in the next few days.  Answers to the questions
above would be helpful, though, in making those modifications.
     However, I don't understand the need for compatibility for tor
controllers on this one.  It seems to me that changes to the ExcludeNodes
and ExcludeExitNodes lists are the kind of thing that should require
rereading torrc, throwing away the previous lists and replacing them with
the new ones read from torrc.  Controllers should have the ability to
trigger rereading of torrc, but not to make this sort of major operational
change on the fly directly rather than by through rereading torrc.
