cvs-version: header-errors with long listnames

[Werk21]

since updating to the cvs-version, a blank line is
inserted into the
headers of lists with long listnames.
the effect is that the header-lines after the empty line are
shown in the mailclient.

It seems to correspondate with the length of the
listname and indirect with
the line-length in the header.

the lists worked correctly before updating.
any ideas?

Example: (you see 2 blank lines after the long lines and
comma)
