Case-sensitive paths collision warning on Mac OS

[rzmz]

Surely this is a minor issue but I get a warning on my console when cloning afresh:

warning: the following paths have collided (e.g. case-sensitive paths
on a case-insensitive filesystem) and only one from the same
colliding group is in the working tree:
