I mean accumulating only on the first `M-.', and replacing the thing
inserted to the minibuffer by the first `M-.' with other things on all
successive `M-.'.  It would be useful to keep the initial minibuffer
input intact, and to insert/replace things within the existing minibuffer
input.

I think `M-.' should not replace the existing minibuffer input, because I
imagine such a situation when the user types e.g. `M-!', types a command
and wants to *add* the thing at point to the end of the command in
the minibuffer.

`M-.' requires more keystrokes than `M-n' only for the cases where
a complex input string is constructed from things at point (like the grep
case).  Thus `M-.'  requires from the user typing the input string,
navigating to the correct place in it and typing `M-.'.

I think a single key is not enough to unleash the full potential
of `M-.'.  I expect that users might want additional keybindings
to yank successive characters/words/lines to the minibuffer.
