I know you know about sed but I don't know you know how to edit multiple
files in-place in a single command in perl. sed is a pain to edit files
in-place as it has to write to a temp file and then typically rename that
temp file to replace the original file.

Nice site.

I don't know how to get your editor to do it and "leave only changed files
open". I suppose it's possible using vim macros but it's not something I
have spent any time learning. I know you know how to edit multiple files
in vim but this is one of the more trivial features of the editor and I
don't know that you know anything about vim macros or have any desire to
learn what is probably a pretty complicated solution for a problem which
can be solved easily with two steps.

I would myself have done the refactoring exactly how I showed it, and
let git keep track of what files have changed.

If it's a problem with leaving the editor open with only changed files,
then I can suggest something like this:

  vim -o $(git status --porcelain | awk ' /^ M/ { print $2 } ')
