What will be the syntax for calling javascript?  And
how can we make sure that calling the javascript doesn't
introduce a security hole?

PmWikiPhilosophy #3 is at its heart very conservative.  The
comment I hear most often from people is that they're glad that
PmWiki avoids bloat, and we do this by avoiding features that
"might be useful" until a need is actually demonstrated.

In this case (:input button:) has three strikes against it:
   - nobody has demonstrated a place where it's needed
   - it requires JavaScript in order to be usable
   - the requirement for Javascript introduces security issues

Since (:input button:) will require JavaScript *anyway*, it
makes more sense for it to be handled as a local customization/recipe
than for it to appear in the core, and have everyone ask
"okay, how can I use it"?

False.  If I put it in, the next set of questions would be "okay,
I see that there's an (:input button:) markup available -- how
can I use it?!?"

The Javascript aspect makes (:input button:) *very* different 
from the submit and reset buttons.
