[Octave-bug-tracker] [bug #62974] The `isa` function returned by imformats doesn't work

[Hartmut]

Follow-up Comment #3, bug #62974 (project octave):

I could reproduce the behavior from comment #0 on my laptop (Octave 7.2.0,
linux). Even when I have a file "example.png" in the working directory, the
first demo code in comment #0 returns me the value tf=0.

After recompiling Octave from the repository (stable branch, Octave 7.2.1),
directly after the patch from comment #2, and also having the png-file in the
working directory, the same demo code in comment #0 now returns the proper
value of tf=1.

So I can confirm, that the patch from comment #2 fixes this issue. Thanks for
your quick response, Rik.
