[patch] fix splitting addresses in repl

[Ruud de Rooij]

Hi,

The addresses in the header generated by the repl command will be broken in
the middle of an address if the address is too long for one line.  This
obviously results in invalid addresses.  For details, Mate Wierdl's post of
30 November 1999 to nmh-workers.

Here is a patch which solves that problem.

Thanks,

Ruud de Rooij.
