Guix,

Before this patch, using PAGER= failed:

  $ PAGER= guix search e
  In execvp of : No such file or directory
  $

With it, it fails in a slightly worse way:

  $ PAGER= guix search e
  $ # nothing, because we spawn the shell that swallows all

Attached are two possible solutions.  One falls back to ‘less’, 
the other to no paging.

I think I prefer the former (‘Ignore empty $PAGER variables’) 
because the concept of ‘unset but empty’ could confuse ‘users’. 
Is that too patronising?  Do tell.

Kind regards,

T G-R
