Loading the slime payload upsets clojure-mode's formatting

[pjstadig]

When given a form like

(deftest ^{:regression true} test-blah
  ...)

clojure-mode will format it by indenting the "..." two spaces from the margin. After M-x clojure-jack-in, clojure-mode will indent the "..." underneath the metadata map.

Repro steps using swank-clojure 1.3.4 and clojure-mode c858a:

1. Format the test source file with clojure-mode, and notice that "..." is indented two spaces.
2. M-x clojure-jack-in
3. C-c C-k to compile the test namespace.
4. Format the source file with clojure-mode and notice that the "..." is indented to line up with the metadata map.
5. Open clojure-mode.el and C-c v.
6. Go back to the test source file, format with clojure-mode, and notice that the "..." is indented two spaces.

After performing a bisect it appears this problem was introduced in cdfc45.

Enabling clojure-mode to respond to indentation-update messages makes it update (get 'deftest 'clojure-indent-function) from 'defun to 1, which is the source of this weird indentation behavior.

The table of special indentations in clojure-mode probably needs to get into swank-clojure somehow (or have :indent metadata set on them in clojure.core).

The hook is so you can write macros, and set ^{:indent n} so they indent properly when used.

If it needs reverting until a swank-clojure side change is made, then so be it.

In case it helps diagnose or point to a fix, this works around the issue https://gist.github.com/182e50836b1e7cd78557 (using checkouts of clojure-mode and swank-clojure)

[technomancy]

Sorry, we've trimmed this out of clojure-mode; it now only contains code for static operations on buffers.
