#2980: r.watershed and max_slope_length

I'm not sure if this is a bug, but I think it might be. The
{{{max_slope_length}}} seems to have no effect in the {{{r.watershed}}}
program. Below is an example that should work on the NC data set. I'd
expect there to be different accumulation maps based on setting
{{{max_slope_length}}}, but they appear identical.
Turns out that this works, but only influences the length_slope output,
not the accumulation output, which is why the example above doesn't appear
to work.

The `max_slope_length` option only affects RUSLE outputs `length_slope`
and `slope_steepness`. From the manual: "This input is used for the RUSLE
calculations".
