I said to look under keywords:

[keywords]
# all items must be in one line
primary=absolute abstract add and array as asm assembler automated
begin byte ca se cdecl char...

There is only the 'primary' keyword set there, so for Pascal there is
only one keyword set possible, hence no word2 style.

To take another example, C:

[keywords]
# all items must be in one line
primary=asm auto ...
secondary=
# these are some doxygen keywords (incomplete)
docComment=attent...

The C scintilla lexer supports 3 keyword sets, so there are three
corresponding styles:
word
word2
commentdockeyword

It's not that easy, the Scintilla (editing component) only supports a
fixed set of keywords for each lexer, some only have one. It could be
that Geany doesn't support all of the Scintilla keyword sets, but
usually we are quite up to date.

What else should we add?
