While running the BISTs of signal 1.4.1 with Octave 6.0.92 on Windows, the
tests for `data2fun` fail:

This is probably because the current directory during the test is the
directory of the .m file. The user might not have write permission for that
directory (without elevated or superuser privileges). Could the current
directory be changed to `tempdir ()` for these tests?

I've marked as Microsoft Windows because I've tested on that OS. But I believe
the error would also happen on Linux if the package is installed in /usr and
Octave runs without superuser privileges.

CC'ing Mike Miller as the package maintainer.
