I use "mce=1,10000000" in cmdline to change the monarch timeout, but
it does not work.
The cause is that get_option() has parsed the ',' already, we need
not to check the ',' again.

get_option(): read an int from an option string;
if available accept a subsequent comma as well.
Return values:
0 - no int in string
1 - int found, no subsequent comma
2 - int found including a subsequent comma
3 - hyphen found to denote a range
