indent with emacs batch mode

Hi Guix,

here’s how people who don’t use Emacs can indent package expressions
nicely.

Save this file somewhere:


[-- Attachment #2: indent-package-expr.el --]
[-- Type: application/emacs-lisp, Size: 288 bytes --]

[-- Attachment #3: Type: text/plain, Size: 576 bytes --]


Enter an environment where Emacs and emacs-guix are available:

    guix environment --ad-hoc emacs emacs-guix

Then run:

    emacs -q --batch -l indent-package-expr.el  bowtie bla blast+

This will properly indent the package expressions for “bowtie” and
“blast+”, and it will ignore “bla”, because that package doesn’t exist.

This is probably a little heavy-weight because it depends on emacs-guix,
which starts a Guile REPL, but other than that it seems to work fine.
