Bug#1334: Another ms-dos tree filename causing problems

[mitchell@mdd.comm.mot.com (Bill Mitchell)]

PACKAGE: distribution site

ms-dos/games/mirrormagic.deb does not stay within the
safe naming convintions of [a-z0-9-_)] chars and 8+3
length limits.  Under PC-NFS, mirrormagic.deb becomes
mirro~4q.deb.
