improve requoting heuristic

First of all, this allows : to be part of a word. This has been added
because the account names start with a colon, so -player :Dunje should
work.

Furthermore, the re-quoting now also quotes strings that contain a .+*,
as those are characters usually used in regular expressions. A command
line like
    raidgrep -- -player "G.dric"
should work, so we either have to re-quote words with a dot, or allow
the dot to be part of a (lexical) word as well. For now, we're
re-quoting it, but if it turns out to be too troublesome, we might
change that.
