It's indeed at least interesting to consider, because at least for .h

simply look in Scintilla's source tree.
+1 for having the headers parsed/lexed by the C++ parser (with sources
it may be a bit dangerous and typically the sources have the right C++
extension).
Not replying to Jiří specifically.
-1. .h is legitimately a C, it's just that many people get it wrong. And
I don't want C++ keywords highlighted in C headers while they are not
highlighted it C source files. This is just confusing.
Why is .h any more C than C++ or Obj-C? Because it came first? I agree
it's stupid that in the later part of last millennium, they decided on
the convention to use .h for C++ and Obj-C (and others?) headers since
it was already a convention in C, but it did become a convention in C++
and now it's widely used, for example [0][1][2][3] among many, many others.
What's more, it's especially useful to see C++ keywords highlighted in
.h header files, since they can be included in C++ as well as C[4][5][6]
unless their author wants to make them less useful by using said
keywords in the header. I think the most common case would be someone
doing it inadvertently (as happened in Geany), which is where having
them highlighted differently gives a visual queue that something is
wrong[7].
