I achieve the same by running two consecutive regex search and replace and a single backspace click

    s/^/"/
    s/\n/“, /

(Change all beginning of line to double pling. Change all new lines to double pling, comma, space)

I don’t even store this as a procedure, I just ctr-f and do it from whatever text editor I’m in (I’m not an Emacs user)

The nice thing about search and replacing your way out of problems is that it works on coworkers machines.

I’m not saying it’s better than a stored procedure or a macro but once you’re into it, it’s easy to regex your way out of all sorts of adhoc problems :)
