I think he want to delete lines matching a regexp, so C-k is not what he
wants here.

`query-replace-regexp' can be used with a regexp like this:

^.*$your_regexp$.*$

and you replace with nothing (empty prompt).

replace-regexp is indeed closer to what I am looking for. However, I'd like the result to not leave blank lines.
