Any objections to the following minor change to the doc makefiles?

Committing this will resolve the problems described in a _very_ old
freebsd-doc PR, which I was discussing with the original submitter
last night.

The problem described in the PR is caused by the ``large'' line-width of
the ASCII text format.  Currently, this is set to 78 characters, but in
sysinstall's dialogs we have at least 2 characters less in each line
because of the dialog decorations.

I completed a full doc/ build today with this patch.  I don't think it
breaks anything very important, so I would be glad if this was committed
some day.
