New version of rst.el

Hi!

I just released version V1.4.2 of rst.el:
http://sourceforge.net/p/docutils/code/HEAD/tree/trunk/docutils/tools/editors/emacs/rst.el

This is mainly a refactoring release with only few user visible
feature changes. I replaced the macros `rst-iterate-leftmost-...` by
the new function `rst-apply-indented-blocks`. I refactored
`rst-enumerate-region`, `rst-bullet-list-region` and
`rst-line-block-region` to use this new function.

During that I improved these commands a bit so they are more in line
with reStructuredText logic.

Thanks to Dominik who pointed out an endless loop in these functions
under certain circumstances. This was my starting point to refactor
all this code.


						Grüße
