What's the actual problem?  I don't see anything wrong - at least
<Tab> still sets the indentation correctly.

An obvious guess is that the "'" character is the problem.  Try
escaping it: " /Today\'s Comic/ ".  Of course I can't test this fix as
I don't see the problem!

ruby-mode.el patched as follows (to fix a different regexp problem):
