Ok, continuing my attempt to get myself off the base-system alias (and
hence getting a significat reduction in my daily spam and uninterested
bug emails quota), and following on from foser's suggestion on an
earlier thread... How about a shell-tools herd? This won't cover shells
themselves, but rather tools that're used from within a shell
environment that don't particularly fit in anywhere else. A not even
slightly complete list of possible packages which are candidates (most
of these are no-herd, some are base-system):

app-misc/bfr
app-misc/color
app-misc/hilite
app-misc/mtail
app-misc/screen
app-shells/bash-completion
app-text/glark
dev-util/txt2regex
dev-util/visual-regexp

There's a load of other stuff in app-misc, app-text and dev-util as
well that would probably belong. You get the idea :)

Maintainer-wise, myself, Ka0ttic, kloeri, slarti`, swegener and taviso
have already expressed an interest, and I'm also kinda thinking about
recruiting someone who I know knows a lot about this area...

(If anyone on base-system thinks I'm trying to steal too much from them,
please scream.)
