OK, I didn't realise that these lexers were being purposefully omitted,
I thought they were simply not present in whatever version of Scintilla
was being used.  Although this becomes apparent after checking out
SciLexer.h which contains the declarations for all the symbols the
left-out lexers provide.  I suppose it makes sense to remove support
for file types you can't immediately utilize.

I'm slightly curious, though, as to the nature of LexOMS (seems to
provide support for Bash?) which is not part of the Scintilla release.

Meh, not really.  I did get to read some fairly interesting source
code.  And now that I'm more familiar with how things work, I can get
started adding some support for other languages I use (like Smalltalk,
Lisp, Erlang) which are in Scintilla but not in Geany.  That is, if the
project is still interested in providing file types in this way?

I guess I didn't explain that very well, here's an example:

[A]

  if (foo) {
  |   bar();

  |   return 0;
  }

[B]

  if (foo) {
  |   bar();
  |
  |   return 0;
  }

Older versions of Scintilla worked like [A], but 1.75 can work like
[B], which I think makes the guide a little more visible (personal
preference).  There may be a knob that needs to get switched somewhere,
though; I know SciTE does this so I'll investigate it for fun.

Hope my many questions aren't too annoying.  Geany strikes me as an
awesome opportunity to build an ideal universal lightweight tool for
programming in any language.  I'm trying to get a feel of how I can
help it grow, and add the features (like more extensive language
support) I think are lacking but within easy reach.

Best regards,
