Sorry, even though english is my first language I speak it with near
`where' was supposed to mean any spots in the code where font-locking
has already stopped working, are not revivied by M-x
font-lock-fontify-buffer. That is, I can see some code with no
font-locking visible in current buffer, but it does not get fixed when
font-lock-fontify-buffer is run.
That isn't quite right either, because some of it does get fixed.
Also with the M-x normal-mode seems to re-font-lock something but not
others. Very confusing and maddening.
If I edit a block where many elements have lost syntax coloring... For
a brief while the syntax coloring is re-established near the cursor
Maybe 2/3 lines in either direction.
Another part to this... not sure if its related is that mic-paren-mode
is now giving false readings at times... I've never noticed that
Any (`) backtick between matching parens (even in comments...) might
cause a false reading it seems

This is the version that came with emacs-23:

Is there something newer or better available?

It appears my version of cperl-mode is not totally outdated eh?.
Any other problems that might cause this? something to do with shadow
paths or whatever its called?
I went to the cperl-mode.el file by calling M-x find-library inside
emacs. So, I guess that means that is the one loading... right.
Any other input would be greatly appreciated... My coding skills are
terrible enough without having syntax coloring problems.
