Follow-up Comment #4, bug #49184 (project octave):
And another addition. This bug appears to have been present in the load path
code for a while, but was hidden by another bug in make_absolute_filename.
The changeset I quoted fixed make_absolute_filename so that works like this:
In Octave 3.6.4 through 4.0.3:
>> cd /tmp
>> make_absolute_filename .
ans = /tmp/
In Octave 4.2:
>> cd /tmp
>> make_absolute_filename .
ans = /tmp
This fix revealed the bug that was always present in load-path.cc, which can
be shown going back to 3.6.4 with the following code (it *must* be / because
of the trailing slash behavior I showed above):
>> addpath /
>> rmpath /
>> cd /
>> cd
>> path
After this command sequence, the load path will no longer contain the "."
entry.
