Oh, I see what the problem is. This is the peril of reusing a generic
dependency parser that has its own ideas of what a valid package name is.
It's actually reducing both substitution variables to essentially the
empty string and then comparing them as equal because they don't look like
package names. Bleh.
I'll figure out some way of fixing the false positive for the next
release, probably by transforming the substitution variables into
something that the dependency parser will swallow.
Sorry about that.
