[Rivet] sherpa/hepevt issue

[Jonathan Butterworth]

Dear riveters,

Vladimir Savinov in ATLAS recently found that there is a hard-coded 
HEPEVT in Sherpa which has length 4000. The fortran generators we link 
in rivet use 10000 (as does ATLAS). The sherpa authors are aware, I 
believe, and hopefully this will be fixed (at least a Genser build with 
10000 should be provided).

It may not affect us, but these things lurk and the common block issue 
has bitten us before, so I thought I had better tell you just in case. 
For instance, if fortran generators suddenly break when you build rivet 
with a sherpa interface...

Cheers,
Jon
