So the CI grabs the first token, upshifts it (not inline) and if it
is '#' or 'COMMENT' does the appropriate echoing to $STDLIST and reads
the next line.

For the CI it does the variable substitution step here, which is
recursive.

Not applicable to the CI.

This will work and should be fully backwards compatible -- well, noting
the fact that $STDLIST output can be different for comment commands than
it is today.  Today, comment lines in $STDLIST have all variables
resolved.  The approach above would cause those lines to appear without
any variables resolved.  I don't know how important this difference is,
but it *may* impact spoolfile scanning tools -- don't know.

Step 1 is what is not done by the CI today -- we don't parse the line
until after substituting all variables.  Since IO redirection is not
acted upon in comment commands this scheme should work fine, given my
$STDLIST caveat above.
