Update of bug #51976 (project octave):

                  Status:               Confirmed => Fixed

Follow-up Comment #3:

I have pushed this http://hg.code.sf.net/p/octave/image/rev/e94c46afdc96 which
will mean that graythresh will now clip those values.

This has the unfortunate side effect of being backwards compatibility since
graythresh was dependent on having values higher than 1 to distinguish between
a vector image and an histogram. vector images are sometimes used to work
around the input check of some functions that require 2d matrices. This was
terrible design from my part, I should had made a separate function to handle
histograms instead of trying to cram everything into graythresh.

This change went into the default branch.
