Opening a new line in evil-mode

Mon Jun 2 16:52:07 CEST 2014

Evil does its best to ensure that the point can neven be at the end of
the line *in normal state*. However, other elisp commands can still
move the point wherever they like, so if you wrap both of those
commands in a function foo, calling foo will exhibit the typical emacs
behavior since evil can't get a word in edgewise (the last symbol is
not carried to the next line). Notice that if you run those commands
one after another with M-:, evil restores its invariant in between,
and you DO get the next last symbol carried to the next line.
