I'd like the output of a command like "guix package -l" to be tabbed 
preserving all columns.

An example output of the current version:
Generation 68	dec 18 2013 12:46:45	(current)
  make  4.0     out     /nix/store/...
  automake      1.14	out     /nix/store/...
  ...

What I would like to see:
  make          4.0     out     /nix/store/...
  automake      1.14    out     /nix/store/...
  ...

The same applies for the output of "guix package -I" and "guix package 
-A"

As discussed on IRC, the rationale (for -I and -A) was to have something
both human-readable and processable–that is, one can pipe it through
‘cut’ and extract the data.  I think that’s an important property, for a
Unix command-line tool.

Now, ideally, ‘guix package’ would be just one of the user interfaces,
with others being more user-oriented than command-oriented (see TODO)...

What do you think?

Hello,

I think a separation between command-oriented and user-oriented
output is a good solution.

Kind regards,
Roel.

Great.  I’m closing this bug, but let’s reopen it if someone feels
there’s more to discuss.
