Fwding to emacs-devel. They are the ones who can change this behavior or
perhaps make the user option move visible somehow.

    Thanks! This always annoyed me, but I've never seen a mention of the
    control variable to turn it off.

    I think the biggest problem with it is the inconsistency between
    incremental search and elisp regexp searches. Literally just yesterday
    I had to debug a problem caused because my practice regexp at the
    command line did what I wanted with a space, but when I used the same
    string in a functional search, it didn't. I've seen the documentation
    for this feature, but wherever it was, it wasn't clear to me until now
    that it was specific to incremental regexp searches rather than a
    general feature of all regexp searches.
