Inline the one call to the get_mode() function.

The get_mode() function was only called in one place, and its
implementation was about three lines. The overhead of checking its
arguments and figuring out its return value was not worth the
absolutely tiny improvement in readability that the function afforded,
so the whole thing has been inlined at its one call site.
