[PATCH ?] gnu: Add dash.

[Tobias Geerinckx-Rice]

* gnu/packages/dash.shm: New file.
---

Guix!

IMO this belongs in a (new) shell.scm with fish, tcsh and zsh.
Maybe bash, too. On the other hand:

Certain shells might have an 'ecosystem' of 'packages', such as
bash-completion in bash.scm, that might justify leaving them in
their own file. I'm thinking specifically of zsh here.

I'd suggest merging them all and splitting out if and when needed,
but prefer to ask the wisdom of the list before doing that tedious
deed.

Kind regards,

T G-R
