It is a feature.  In the old days of the Apollo OS two leading slashes
identified a network path.  In the consolidation of operating system
feature sets that feature was preserved and is still possible
depending upon the system.  It is allowed but not required.  Your
system may not use the feature but others do.  More recently Cygwin is
making good use of it in the Cygwin environment for the same purpose.

Therefore the standards say that two leading slashes are significant
and are handled specially.  It might be a network path.  But three or
more leading slashes are not significant and anywhere else in the path
multiple slashes are not significant.
