it can be a solution, though: re-builder supports different forms of input
syntax. by default, it requires you to escape backslashes, so that when you
type C-c C-w to copy the regexp to the kill-ring, you get it with every
backslash escaped.

if you don't want to type the double backslashes, you can change
re-builders input syntax (with C-c TAB)from "read" to "string". then,
before typing C-c C-w change it back again to "read": re-builder will
automatically adjust the syntax and escape all backslashes for you.

it's a pretty neat package, that re-builder.
