Currently, we may either trace syscalls or syscalls+pagefaults. We'd
like to be able to trace *only* pagefaults and this commit implements

Firefox doesn't correctly handle cases where we specify number in
quotes and have some padding around the number, like the following:
In this case, it doesn't draw the figure. This patch removes 'field width'
