evil: work on support for ]p, [p (adjust indent on paste)

[Johann Klähn]

(Sorry to everyone, seems my subscription to this list did not go through
so I haven't been received your answers. I just stumbled across them via
the gmane archive. Thus the reply-to-self.)

Gordon, Frank, thanks for taking the time to answer.
I originally tried to define a command as Gordon mentioned (see below), but
this lead to two separate undo steps (pasting and indenting). Regarding
evil-paste-pop I think I like the :paste-command suggestion most, I may end
up implementing that. As I am short on time currently, I likely won't get
to it this month.

(evil-define-command evil-paste-before-adjusting-indent
  (count &optional register yank-handler)
  "Like `evil-paste-before' but adjusts the indent to the current line."
  :suppress-operator t
  (interactive "P<x>")
  (evil-paste-before count register yank-handler)
  (my-evil-adjust-indent-after-paste 'before))
