You have interactive_comments set, right?
This should fix that (I haven't looked close enough to find out when
it did that and when it didn't).
There is still something fishy, though. A string like `ls (#i)foo' is
broken into `ls' and `(#i)foo', but `[[ (#i)foo ]]' is broken into
`[[', `(', `#i', `)', ... I haven't found out where and why this
happens yet.
