[gentoo-dev] [PATCH] user-info.eclass: egetent: fix lookup by id when ROOT != /

[Mike Gilbert <floppym@gentoo.org>]

Previous to this change, egetent would match any id that starts with the
id given as input. For example:

egetent group 1

bin::1:root,bin,daemon
wheel::10:root
floppy::11:root
news::13:news
uucp::14:uucp
console::17:
audio::18:
cdrom::19:
users::100:

Adding a colon to the grep expression yeilds the desired result:

egetent group 1

bin::1:root,bin,daemon
