Add support for smart-dash-mode.

Description

It's a hard one because we delete the inserted character but smart-dash-mode checks the previous character in the current buffer. It's even harder to solve this using general rules.

Experiment

The example:

foo->bar

At the dash it inserts a underscores '_' which will be marked as error. At the > the underscores isn't replaced by smart-dash-mode because the previous character is a dash not the underscore.

Idea to solve it

There could be a solution allowing for "replaceable characters". This way the input actual overrides the character in the speed-type-buffer and the "orig-char" would be stored as property. The character would still be marked as error until the "orig-char" matches it. Then when comparing we would check the property value of orig-char, if the value does not exists we would just check the character as usual.
