tlug: bug in xlock

[Scott Stone <sstone@example.com>]

Xlock has 2 serious bugs that I've found now (both with easy workarounds).

If there's a blank line in between two entries in /etc/passwd or in
/etc/group, SIGSEGV.

If DISPLAY is not set, SIGSEGV (come on, that's so easy to trap, geez..
just check if XOpenDisplay returns NULL...)

At least, it affects the Xlockmore-GL package, maybe the bare-bones xlock
doesn't have this problem.  I'm going to try fixing it tomorrow and making
a new package...
