More emacs-style keybindings in edit widget

[hpdeifel]

Some bindings that would be nice to have:

• C-b: Move one char backwards
• C-f: Move one char forward
• M-b: Move one word backwards
• M-f: Move one word forward
• M-DEL: Delete previous word
• M-d: Delete next word

• C-w: Delete previous word
• C-u: Delete to BOL (instead of: Delete entire input)

Not an emacs-binding, but readline:

• C-d (in the Date-Input-Box): quit

Thanks!

C-u: Delete to BOL (instead of: Delete entire input)

True. I already implemented this for brick but forgot to remove the workaround binding in hledger-iadd.

C-d (in the Date-Input-Box): quit

That's already implemented since yesterday 😄. It now does the same as C-c everywhere: Directly quit in date prompt and ask in all others.
