Alacritty: Double-click selects trailing tab

[sersorrel]

Run this:

$ printf 'select\tme\n'

and double-click select. Observe that the cell after the word is also highlighted, and pressing ctrl-shift-C will copy the tab character.

I've verified this on the latest master branch.

Adding \t to semantic_escape_chars in alacritty.yml fixes this for me.

Sounds like that might be a reasonable change. I don't see why it wouldn't be part of it already, since a normal whitespace is already in there. So likely just an oversight.
