This request is exactly as bug#14729 - to change the traditional behavior
of isearch for no gain, only for consistency with some abstract ideas.

The patch implemented automatic case-fold toggling in both directions,
where typing a letter re-evaluates case-sensitivity of the search string.
This might break some users' habits.  So another idea was to re-evaluate
case-sensitivity only in `isearch-edit-string' and `isearch-del-char'.
Still such change might be unexpected for some users.
