Otherwise, syntax-wholeline-max seems to be doing its job fine: if I
comment out the narrowing code in handle_fontified_prop (or switch to
the branch I posted previously), two XML files -- one with long lines
and one without (the files differ only by addition of newlines) -- show
approximately the same delay on M->.
Doesn't syntax-wholeline-max only affect long lines?
Its purpose is to handle the slowdown which occurred specifically on
long lines because of
font-lock-extend-region-functions/syntax-propertize-extend-region-functions.
Now that it works -- I don't see any particular slowdowns on long lines,
even with narrowing disabled.
And the performance of M-> depends solely on the size of a file. In my
XML test files, at least.
