TypeAhead Fix

[schinagl]

General

With #290 TypeAhead was fixed, but we all overlooked one use-case

Problem

Assume you have the following files in a directory

as
bla
san
system
syxsser
zzz

The attached .bat file creates such a situation.

• Select 'bla' in the right pane
• Type 's' 'y' 's'
• The cursor is on 'syxsser' which is not correct. It should be on 'system'

About the changes

With #290 we overlooked, that only consecutive same characters shall move the cursor ahead by one. The #290 solution also moves ahead by one, if any character typed within a word is the same as the first, but other characters are in between.

I now cross checked the fixed behavior with explorer and it is exactly the same.

The behavior looks good. A couple of small things to fix.
