samples keyword arg ignored in FreqDist.tabulate

[rdbliss]

It looks like the samples keyword argument mentioned in the docstring of FreqDist.tabulate() is ignored. Is this the intended behavior?

Here are the arguments from the docstring:

:param samples: The samples to plot (default is all samples)
:type samples: list
:param cumulative: A flag to specify whether the freqs are cumulative (default = False)
:type title: bool

Here's an example of samples being ignored:

from nltk import FreqDist

fd = FreqDist(["foo", "bar"])
# I expect to get just "foo", but get "foo" *and* "bar".
fd.tabulate(samples=["foo"])

This is different from what ConditionalFreqDist.tabulate() does, so I'm not sure what's intended here. Either way, it would be nice for the docstring to be clearer.

Can I start working on this ?
