[bug#30053] [PATCH 1/3] Improve appearance of tabular output.

[Danny Milosavljevic]

Hi Ludo,
Hi Steve,

terminals support setting tab stops.  The user could (and arguably should) just 
set them (see tabs(1).  Example invocation: "tabs 1,20,25").

Also, they are columns in a TABle.

There's also "column -t" which one can pipe the output to, which will take care 
of autosizing the columns. 

It's typical of UNIX tools that they prefer machine readability to usability.  
There are always small tools like the ones above one can use (either before the 
invocation or after the invocation) to make output more usable.

That said, Steve even retains the tabs, so both use cases would be supported.  
The only cost is that with the patch there's a lot of whitespace printed in 
columns that's actually not in the database at all.  But that's OK I think.

Also, "guix package -A" (even before the patch) eats up all my 8 GB of RAM on 
guix master and then my computer hangs.  What's up with that? (I tried it 3 
times now - it's reproducible) O_o
