Hi Arun,

Why is it a problem that two or more dots are prepended to them?

It means that 'foo' and '.foo' will have the same generated file name
'.foo-real'.  Wrapping a hidden file and its non-hidden counterpart is
something that probably shouldn't happen, but if for some reason it must
happen, we'll face an annoying bug.  WDYT?

Clément
