1. emacs -Q
2. eval the following:
(electric-indent-mode)
(electric-layout-mode)
(setq electric-indent-chars (append "{}" electric-indent-chars))
(setq electric-layout-rules '((?\{ . after) (?\} . before)))
3. type `f o o {'
Result expected: a buffer containing
----- schnipp -----
foo {
----- schnapp -----
Result received: a buffer containing
----- schnipp -----
foo{
----- schnapp -----
Patch is enclosed that fixes the problem.

I must be missing something:
- your patch does not seem to make any difference to your test case.
- I don't understand why you'd expect `f o o {' to end up inserting
a space between foo and the open brace.

Sorry, the test case is wrong; you're supposed to type `f o o SPC {'

Well, the problem I see is that you left the call to line-beginning-position where it was in the original call. At that point, point may be on a different line than it started on, so it’s actually getting information about the wrong line. It’s possible that your patch somehow makes everything work out, but leaving the call to line-beginning-position where it is seems at best fragile to me.

On the contrary, moving the call like you did was wrong, IMO. The test
against line-beginning-position is meant to check if pos is on
a previous line, in which case we also need to reindent that previous
line, whereas with your patch it reduces to just check if pos is at
(bolp) which is not as interesting (tho it will often work as well for
the newline case).
