I think we can all agree that crashing in a function like that is a bad
idea, but there's not much we can do here. API users should check their
input for validity.

But there's a deeper philosophical problem here:

    c:Software/SourceCodeRepository

is actually a valid path on Windows; however it's neither an absolute
nor a relative path but that hybrid mutant called a "device-relative
path". In other words, it might or might not work, depending on context.
Technically we /can/ construct an absolute path but the result will
change depending on OS context that we have no control over.
