[PATCH] emacs: devel: Add indentation rules for 'modify-phases' keywords.

[Alex Kost]

Hello, currently Emacs indents our 'modify-phases' macro like this:

(modify-phases %standard-phases
  (add-before 'build 'foo-phase
              (lambda _ 'foo)))

or this:

(modify-phases %standard-phases
  (add-before
   'build 'foo-phase
   (lambda _ 'foo)))

While IMHO it is better to have it indented like this:

(modify-phases %standard-phases
  (add-before 'build 'foo-phase
    (lambda _ 'foo)))

This patch will do it.  Of course we can just use:

(put 'replace 'scheme-indent-function 1)
(put 'add-after 'scheme-indent-function 2)
(put 'add-before 'scheme-indent-function 2)

But potentially these keywords may also be used outside 'modify-phases'.

So with the attached more complex rules, 'replace', 'add-before' and
'add-after' keywords will be indented specially only when they are
inside 'modify-phases', otherwise they will be indented as usual:

(modify-phases %standard-phases
  (replace 'build
    (lambda _ (zero? 0))))

(do-something
 (replace 'this
          'that
          'and-that))
