jove 4.9 (regular expressions won't turn off)

[Rob McMahon]

I hesitate to call this a bug, because the code is so deliberate.  If anyone
can justify this for me, I'd love to hear from them.  Turning off
match-regular-expressions doesn't turn off all the magic characters, which
certainly surprised people round here when they tried to search for a string
containing a `$'.  The code in question, however, explicitly only disables
".[*", leaving ^, $, \{, \}, \(, \), \|, \digit, \<, \> enabled ?  I can
almost understand the \? constructs, people who use Unix learn that \ is
magic, but ^ and $ ?  Anyway, here's my current fix, I'd like to hear your
opinion.
