[pmwiki-users] Question about StopWatch usage

[Tony C.]

Recent emails have suggested to enable/display PmWiki's stop watch
function by doing (if one only wants the wall time):

$EnableDiag = 1;
$EnableStopWatch = 1;
$HTMLFooterFmt['stopwatch'] = 'function:StopWatchHTML 1';

The documentation at http://www.pmwiki.org/wiki/PmWiki/DebugVariables
says:

The timings can be displayed by adding <!--function:StopWatch--> in the
wiki template.

As far as I can tell, the correct thing to add in the wiki template is:

<!--function:StopWatchHTML X-->

where "X" can be anything but "0" (zero), space, or nil.

I've just tested the $HTMLFooterFmt, and it behaves the same way, i.e.
anything but zero, space, or nil results in (the same) output in the
footer.

Is the documentation simply out of date and it's ok if I fix it?

Why would I ever want to put zero, space, or nil there? 

Unless there is a good reason to ever put zero, space, or nil there,
why have that "argument" at all?

I have no control over anything that appears after this sentence.
