#57850: octave @4.4.1_2: Error message when starting Octave.app and broken online
help using the doc function

 When launching the Octave.app GUI, a message window pops up with the
 following error message:

   Could not copy help collection to temporary file. Search capabilities
 may be affected. Cannot create index tables in file

 After clicking on OK, the Octave GUI opens. Octave primary functions seem
 to work without problem except for the {{{doc}}} function (which was
 hinted by the error message). Asking, e.g., for the documentation of the
 {{{deg2rad}}} function will only display two empty panes in the tab
 "Documentation" instead of the requested page from the online version of
 the manual. Related may be that the menu entry {{{Help->Documentation->On
 Disk}}} is not working as expected -- only the two empty panes from the
 Documentation tab are shown.{{{Help->Documentation->Online}}} opens the
 Octave manual from http://octave.org in a web browser.

 When using {{{octave}}} from a regular shell, the above error message is
 not shown and the {{{doc}}} command works as expected displaying the
 online manual in the {{{info}}} browser. I am using the {{{octave}}} port
 already for several years every couple of weeks, but I never noticed the
 error message before. Therefore, I suspect that the error got introduced
 by one of the recent updates to the port.

 The exact variant of the port, which is installed is:
 $ port installed octave
 The following ports are currently installed:

 My MacPorts installation is fully updated and runs on macOS High Sierra
 10.13.6 on MacBook Pro 15-inch 2017.
