Although according to POSIX
Enclosing characters in single-quotes ( '' ) shall preserve the literal
value of each character within the single-quotes. A single-quote cannot
occur within single-quotes.
so "!" should be not treated as special character in POSIX shell,
csh unfortunately does not follow this. Try
$ echo '!!'
in csh, tcsh (now that's funny) and bash (or dash).
