Undo auto-space insertion when entering special characters

[Johannes Kempf]

A space is added by default while choosing a word from the word-ribbon when auto-suggestion and auto-correction enabled. If the next typed character is a punctuation mark the unnecessary space is removed automatically. For other special characters the space will remain: e.g. at-symbol @, dash -, or underscore _.

This is very annoying when you're typing email addresses.
As it is very uncommon to start a word with these characters it would be better to remove the automatically inserted space.

Remark: Please do not treat them like punctuation marks in every circumstances. Auto-suggestion inserts a matching word when choosing a punctuation mark while typing a word. This isn't done for other special characters. Here is the current behavior very useful.
