Messages should not contain the `\v' escape?

[Sergey Poznyakoff]

Hello,

In some cases messages could legitimately contain the '\v' escape.  One
of such cases is the use of GNU argp_parse function, for which this
character means "output the following text after the list of the
options".  The GNU projects using this feature include: tar, cpio,
radius, mailutils and cflow.  If there are no strong reasons against
allowing the use of `\v', I'd propose the following change:
