[Octave-bug-tracker] [bug #65442] legend.m fails on polar plot when executed more than one time

[Markus Mützel]

Follow-up Comment #5, bug #65442 (group octave):

Your patch looks good to me in general.
Just a minor remark with respect to the general coding pattern when it comes
to unwind_protect-blocks: Afaict, variables that are used in the
unwind-section are usually defined *before* the start of the protected section
of the code.
Could you please move the line that defines `hvisibility` to before
`unwind_protect`?
