[stefan.schuerger: Path problems with trailing dot]

----- Forwarded message from Stefan Schuerger -----

Today I noticed with streamripper that Cygwin appears to have a problem
with trailing dots in paths:

> mkdir test. ; echo > test./test2
bash: test./test2: No such file or directory

The trailing dot disappears and cannot be used in paths. This seems to
be a DOS legacy of either NTFS or Windows.

Is there anything in the queue to fix this?

Regards,

Stefan Schuerger

Pierre, Corinna,
As the above email illustrates, we are specifically treating a foo.\bar
as invalid in path_conv.  I don't remember the rationale for doing this.
It seems inconsistent to do this given the above example.

The patch below reverts this behavior on non-NT systems but it is
obviously not the right behavior for NT due to the fact that NtCreateFile
doesn't consider "foo." == "foo".  Do either of you remember why
we (i.e., I) did things this way?
