The main goal of quote() was to prevent the CI from interpreting
certain meta-characters, like double quotemark, single quotemark,
exclamation mark, etc.  There had been some discussion at the time
of having a HpCINoMeta variable that would tell the CI to not
process any meta-characters in the command line, or making this
a UDC/script header option, etc.  This would have been useful, for
instance, where one script creates another script.

The short-lived quote() function was an attempt to deliver on
that concept. But, there were problems with quote: it blindly
doubled quotemarks, even when that wasn't correct -- e.g.,
inside ![expression] clauses. Another problem is that if
you have a string with single and double quotemarks (say, as
an info= string) you don't necessarily want both types of
quotes doubled -- you probably only want to double the type
of quote you are choosing to enclose the entire info= string.
So, quote() had some problems and a more reliable and predictable
approach is to use repl().
