[Octave-bug-tracker] [bug #51632] make global pkg paths always relative to OCTAVE_HOME, no need to pkg rebuild -global when path changes

[Markus Mützel]

Follow-up Comment #45, bug #51632 (project octave):

@Philip: I don't know where you have that information from. But short file
names don't work like you describe. See e.g. this Microsoft article about
disabling them for a performance increase [1] - albeit with a compatibility
warning for older programs.

As a final proof that I'm not hallucinating ;-)

"D:" is an internal drive, "E:" is an external USB drive. Note that the column
that shows the short file name is empty on D:.

But you are right. This is off-topic.
