1. I and others have requested this for vanilla Emacs a few times,
as a user toggle.  E.g.:


2. In Icicles at least, you can use `C-M-.' to toggle what `.'
represents in the minibuffer (i.e., for most interactive use).  When
`.' matches also a newline, it appears as `.' in the minibuffer, but
the actual regexp used under the covers is "\(.\|[
]\)".  (When this is the case, it is also highlighted, so you can tell.)

IOW, when newline is also being matched by `.', this propertized string
is inserted in the minibuffer when you type `.':

]\\)" 0 10 (face highlight display "."))

Not the ideal solution (hence the requests cited), but handy enough.
