Highlighting of .idl-file fails if .idl contains preprocessing
directives (#ifdef, #include etc.)
For example:
./exam.idl:
#include "other-module.idl"
module M {
}
$ enscript -v -E -whtml -p result.html ./exam.idl

The problem is that c_ppline state used from idl state depends on c.st
for special state CHighlight (declared in c.st) but does not fulfil this
dependency by explicit require_state ensure does not ensured in
c_ppline.st itself.
(Which is obviously because all other c_ppline usages occurs inside
c-related states).
Patch to fix unresolved implicit dependency of c_ppline.st state on c.st:
