I know several tools go this way, but actually prefer one or more "-f
<fieldname>" args, and an "-s <seperator>" (or -0 for a nul) arg.  That
makes getting a single field very easy, without doing formatting in xend
which people might start to rely on.

This is analogous to the "old modinfo" vs "new modinfo" where I decided
to do it this way.

Cheers,
Rusty.
