Forgive me if this problem was already reported ago.

Emacs version is 18.55.

The problem happens in some regexp-search concerned functions when
null-space-line regexps

        ^$

is given.

For example, once isearch-forward-regexp (Meta C-S) finds it successfully,
trying to search one more by typing ^S does not move the cursor to the next
occurrence but sticks it on the current line.

One more example.  The function

        (delete-non-matching-lines "^$")

will fall into endless loop at the first null-space-line position.

Thank you.
