Processing the file ifv.1 below with

    (woman-find-file "ifv.1")

puts a warning in *WoMan-Log*

    **  if v -- unrecognized condition name rejected!

where I thought it might quietly treat ".if v" as false.

According to the groff manual "v" is "-Tversatec" output, whatever or
wherever that is.  Perl pod2man generates it for some accenting with a
comment that it's "for vroff".  Perhaps woman could treat it as false
the same as groff
