On second thought (or third thought) I don't like this because it
matches cases where there are two division operators in a single
expression, such as:
document.write('<table><tr><td>25% = '+(25/100)+'</td></tr></table>');
mh... I'm not sure I understad: why does this happen? The other / are
in strings delimited by '', aren't they?
document.write('<table><tr><td>25% = '+(25/100)+'</td></tr></table>');

When at this point in the line, the "regexp" rule will match instead of
the "string" rule. I.e., the "regexp" rule will match with an empty
prefix, while the "string" rule would have a nonempty prefix before the
string starts:
document.write('<table><tr><td>25% = '+(25/100)+'</td></tr></table>');

document.write('<table><tr><td>25% = '+(25/100)+'</td></tr></table>');
