--- Now that we also use lpeg lexers in scite, we can share the keywords

--- boil down to doing similar things, but here we need more control over

--- that the coloring looks similar: both are derived from earlier lexing (in
--- texedit, mkii and the c++ scite lexer).

--- In the meantime we have lpeg based lexers in scite! And, as all this
--- lexing boils down to the same principles (associating symbolic rendering

--- sense at some point to share code. However, keep in mind that the pretty
--- printers are also supposed to support invalid code (for educational
--- purposes). The scite lexers are more recent and there a different color
--- scheme is used. So, we might move away from the traditional coloring.
