This is fixed in CVS. Thanks.

This is a valid point but not so easy to fix.

Maybe I should add warining messages to safe_replace and
quoted_regex_parse functions.

Now the VCS version does not print out as much.  But this is problem I

Now that 2 trivial bugs are fixed, let me retitle this bug as this.  So
I will work on this later.
