Details:

Hello,

I'm translating the Grub man pages into German [1]. Using po4a [2] for
creating gettext catalogs, the following part of grub-mknetdir.c produces an
error message saying that \v shouldn't be part of a translatable string:


struct argp argp = {
  options, argp_parser, NULL,
  "\v"N_("Prepares GRUB network boot images at net_directory/subdir "
         "assuming net_directory being TFTP root."), 
  NULL, grub_install_help_filter, NULL


The »\v« goes literally into the gettext message. But obviously it doesn't
have any purpose. It is neither visible in the output of »man grub-mknetdir«
nor in the output with --help (which is actually the source of the man page
because you use help2man), it is shown as a non-printable character when I
view the unpacked Groff source in a text editor, and the HTML output shows a
question mark [3][4].
