I think in (wgrep-prepare-to-edit)  we should use a regexp like
(string-match "^\\([a-zA-Z]?:?[^:]*\\):\\([0-9]+\\):\\(.*\\)" Line) to determine whether or not to set read-only property

Hmm, is this a windows problem?
I'm not sure what you are exactly saying.

I guess this problem was fixed in #11.
