[tex-live] TexLive version of CWEB can't handle strings >1024 characters

[Karl Berry]

Hi Arthur,

    http://www-cs-faculty.stanford.edu/~uno/cweb.html
    In this version (dated 2008-04-28), "longest_name" is defined to 10000.

Thankfully, that version
(ftp://ftp.cs.stanford.edu/pub/cweb/cweb.tar.gz) matches what is on
CTAN, in web/c_cpp/cweb.

I just updated the longest_name value in TL's cweave.w to match that
original.  There are a variety of other discrepancies to be ironed out,
as I noted incorrectly in the ChangeLog, but this seemed to be the only
case where the TL value is less than the original.

Thanks for the report.
