Details:

AFAIK addpath() normally recognizes if its argument is already in the PATH and
if so, doesn't add it to the PATH a second time.
But on Windows, where both '\' and '/' are accepted as file separators and
path-/filenames are case-insensitive, it gets confused by different fileseps
and different case in otherwise identical arguments, so the PATH can end up as
follows:

>> path

Octave's search path contains the following directories:

.
C:/Users/Philip/Desktop/getij/m-files
C:/Users/Philip/Desktop/Getij/m-files
C:\Users\philip\desktop\getij\m-files
C:\Programs\Octave\OCTAVE~1.0_2\mingw64\share\octave\packages\windows-1.3.1
:


Of course it's no big deal, Octave works fine anyway, but it is unneeded
cluttering of the search path.

Severity => Minor
