add meow-duplicate and duplicate-and-comment

[eshrh]

I have written a rudimentary pair of duplication functions that basically save and then yank.

This is basically like crux-duplicate-current-line-or-region from crux, but implemented with meow functions instead. I have found this very useful after I wrote it for myself.

The current duplicate function duplicates a char instead of a line like crux when no region is active. I think this makes sense because selecting a line is natural and common but selecting a char is more awkward (expand right).

I think this is a good candidate for P in suggested keybindings which is currently free [not in commit (yet)]

Any thoughts on this?

Hey, sorry, I'm against this proposal.

There are some reasons:

1. This is a normal DWIM command, and meow is against this. The command should be separated as for single char, and region.
2. This command affects the kill-ring, which is unnecessary.
3. meow-duplicate-and-comment is too complex for its functionality.

And the most imporntant, I don't think meow should cover all the operations. Meow itself is build with operations around a "selection" concept, some features will indeed be missing here, but that's acceptable. I don't think meow has to be a replacement for all editing packages.

ok, sounds good. this is fairly trivial to write for a personal config anyway (it's actually straight from my config).
