M-p should have the same effect: the "mode" is only a default for a new
search. If the last search was a regex search, it'll put in you regex
search mode.
But what about keeping current behavior where C-M-s M-p pulls only
regexps from the regexp history. Should we break backward compatibility
in how it used to work?
I think that behavior is an artifact of the current implementation, not
something desirable.
String and regexp searches are fundamentally different in nature.
Why? I use them as different ways of accomplishing the same goal:
finding something in a buffer.
Regexps are useless in string-based modes, whereas strings in isearch
are interpreted by different rules according to mode: word/case-fold/...
e.g. it makes sense to switch from case-fold mode to word mode, but
not from regexp mode to literal mode.
But people _do_ switch from regex to literal mode and back. That's why
M-r is a convenient isearch binding for doing exactly that, and on
prevision occasions when this topic has come up for discussion, others
have indicated that they use this M-r binding.
But it you want to share string and regexp histories, it's easy to implement
by another layer of indirection like for query-replace history variables:
(defcustom query-replace-from-history-variable 'query-replace-history
(defcustom query-replace-to-history-variable 'query-replace-history
Sure. It's possible to make this behavior customizable.
