Request: Be compatible to align-regexp

[theldoria]

The idea behind an interactive align function is really great. However, I wished it would be fully compatible to align-regexp, that is it should be possible to use the very same regexp to generate the exact same aligning.

You mean when you navigate through history with M-p, M-n, you also
want to restore the group, spacing, repeat argument, etc?
I think read-from-minibuffer can only restore the text from history and
there's no pop-history-hook or something so a hack is necessary. I will
try to come up with something though.
