I'm reporting this for a Ubuntu user.

1)
[EMAIL PROTECTED]:~$ lsb_release -rd
Description: Ubuntu 8.04.1
Release: 8.04
2) [EMAIL PROTECTED]:~$ apt-cache policy grep
grep:
Installed: 2.5.3~dfsg-3
Candidate: 2.5.3~dfsg-3
Version table:
*** 2.5.3~dfsg-3 0
500 http://au.archive.ubuntu.com hardy/main Packages
100 /var/lib/dpkg/status
3) Only whole words returned. There were a couple of spurious results in a
large grep. Example file (from Linux kernel) is enclosed, and as you can see,
piping through same grep expression again "fixes" the problem.
4) [EMAIL PROTECTED]:~$ grep -w alloca devel/kernel/linux-2.6/kernel/pid.c
* Generic pidhash and scalable, time-bounded PID allocator
