Nit: While this may indeed be a case for which an explanatory comment
is justified, the comment itself is a bit lacking -- just enough to
keep it from being helpful for the next person who comes along to work
on this code. For instance, the too-abstract "some ls implementations"
doesn't provide enough information to point at a specific 'ls'
implementation if a person needs to do testing against one of these
implementations or wants to know if (say, several years from now) that
anomalous behavior is still present. It would be helpful, therefore,
to mention such an implementation by name:
...some 'ls' implementations, such as on FreeBSD, include...
(One can, of course, always argue that the commit message can be
consulted to learn about a particular 'ls' implementation, but then
why have an in-code comment at all?)
