Guix command line flag consistency

[Mike Swierczek]

Hello.  I started taking GuixSD for a spin and love it.   Thanks for all 
of your work!

I hope this question isn't too elementary.

I see that the 'guix package' command line tool, and possibly all of the 
Guix command line tools, use the Scheme SRFI 37 convention for argument 
handling.   It seems a little unintuitive to me as an outsider trying to 
learn Guix.  I wrote 'guix package --search git' and got an error message.

I'd much prefer if both the short and long command line arguments 
accepted their argument in any arrangement.
--long-flag=foo
--long-flag foo
--long-flagfoo
-short-flag=foo
-short-flag foo
-short-flagfoo

Obviously this is a headache for the persons writing the command line 
parser.  But I think it's more friendly to people new to the project.  
What do you think?
