Ah, sorry. I had pushed "Post" button.
But subtitle says all.

Hi,

I also found some problems in regexp_nfa:

1. Character classes such as [[:cntrl:]] or [[:alpha:]] may match
multibyte character unexpectedly.
2. Debug log (postfix notation) may contain garbage outputs.

Attached patch fixes them.

Thanks,
Ken Takata

Thanks. There are more allocation and size problems...

Thanks! My syntax file tests clearly don't have enough variety to catch
all bugs.

LETTERS TO THE EDITOR (The Times of London)

Dear Sir,

I am firmly opposed to the spread of microchips either to the home or
to the office.  We have more than enough of them foisted upon us in
public places.  They are a disgusting Americanism, and can only result
in the farmers being forced to grow smaller potatoes, which in turn
will cause massive unemployment in the already severely depressed
agricultural industry.

Yours faithfully,
        Capt. Quinton D'Arcy, J. P.
        Sevenoaks

Thanks. BTW) I was thinking that vim's regexp engine can't handle CJK
class names like [[::katakana::]] and it's nessecary for CJK people.
Some regexp engine support CJK class names.
How about to add this?

Let's fix bugs before adding new features. There are too many bugs
right now.
