#12257: 1.0*pi should *not* be pi

This is really bad
{{{
sage: 1.0 * pi
pi
sage: sin(1.0 * pi)
0
}}}
This is good:
{{{
sage: maxima('sin(%pi*1.0)')
sin(1.0*%pi)
sage: maxima('1.0*%pi')
1.0*%pi
}}}
This is likely the fault of ginac doing something stupid with 1.0 == 1.
Ken Ribet pointed this out during the JMM 2012 meeting.
