Incorrect information in the manual about the tar-v7 option

[Vincent Lefevre]

Hi,

The automake manual (several versions) says about the tar-v7 option:

     `tar-v7' selects the old V7 tar format.  This is the historical
     default.  This antiquated format is understood by all tar
     implementations and supports file names with up to 99 characters.

This is incorrect. Old versions of BusyBox (such as v1.6.1, currently
used on Nokia's Internet tablets) don't support this format. See:

  https://bugs.maemo.org/show_bug.cgi?id=3033

Shouldn't tar-ustar be the default instead of tar-v7?

Regards,
