You've rubbed out my after-change function! Heeeellllllllllpppppppp!!
The after-change function is needed to set syntax-table text properties,
since this must be done regardless of whether font lock is enabled. In
fact, it's a massive pain in the posterior that font lock erases these
text properties without getting permission from the major mode. This is
the only reason that c-awk-set-syntax-table-properties is hooked into
font-lock-syntactic keywords - essentially, the syntax-table properties
are an after-change thing.
I don't want to mix up the syntax-table and f-l-multiline properties,
because they're very different things. Doing so would weaken the
existing functions, which are strong single-purpose functions. To do
things this sort of way, I'd put in a new function
c-awk-set-fl-multiline-properties (a sister function to
c-awk-set-syntax-table-properties, with the same calling conventions).
The existing function loops round string/regexp/division sign constructs,
whereas the new one would be looping round lines. They don't mix very
happily.
But mainly, I don't want to be applying f-l-m properties throughout the
region[*]. They should be applied only at the region boundaries when
these need extending, and only when font lock is enabled, since they serve
no purpose otherwise.
[*] As you're aware, I don't want to use f-l-m properties at all. But if
I must use them, I only want them where absolutely needed.
And you've rubbed out my before-change function! Ruuuuuunnnnnnnn
awwwwwaaaayyyyyyy!!!!!!! This is needed for other things besides
calculating font lock boundaries.
Why not leave things alone until Richard has settled the whole matter?
