#8121: preparsing of "time" special command inconsistent in company of
parenthesis
------------------------+---------------------------------------------------

------------------------+---------------------------------------------------
On the Sage (=IPython) command line:
{{{
sage: time (2+2)/3
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s
4/3
sage: time(2+2)/3
...
NameError: name 'time' is not defined
}}}
In the notebook
{{{
sage: time (2+2)/3
...
NameError: name 'time' is not defined
}}}
This is happening because in some cases Sage treats "time <foo>" as a
function call, and sometimes not. In the notebook it is always a
function, when <foo> starts with a paren, but on the command line it is a
function only if there is no space between time and (.
FIX: Make the notebook work exactly the same was as the command line, in
this instance. That seems like a reasonable solution or compromise.
