[PATCH] revised verbatim-handling code

Hello,

I found some minor issues regarding the verbatim handling, so I  
revised the verbatim handling code. The issues and my changes in short:


- verbatim_begin_regex matches more than "#v+".

I think the "#" and the "Plus" has to be escaped  
(DEFAULT_VERBATIM_*_REGEX).

NOTE: If the tinrc already contains verbatim_*_regexes these values  
will be used (not the new DEFAULT_VERBATIM_*_REGEX values), so in  
this case the user has to change this in the config-menu by hand.


- Rot13 does not rotate the verbatim_begin_regex line but the  
verbatim_end_regex line.

The line that matches verbatim_begin_regex was part of the verbatim  
block, the verbatim_end_regex line was not part of it.

I changed this so that only lines _between_ verbatim_begin_regex and  
verbatim_end_regex are part of a verbatim block (-> rot13 rotate the  
regex-lines like the normal article body but not the verbatim block).


- I changed "verbatim" to "in_verbatim" (like in_sig, in_uue etc.).


- Lines within a verbatim block now gets the C_VERBATIM flag, whether  
HAVE_COLOR is defined or not (like C_SIG, C_BODY), so all article- 
lines have a dedicated flag independent of HAVE_COLOR.

Please find the patch attached.

Regards,
Dennis
