This is a change which causes us pain regularly. The defaults in previous
cygwin versions worked well and where predicatable from both a coding
and user perspective.

So we would have to agree with the author here that the current behavour
should be reviewed and reverted to the much safer and more expected
defaults where by only execution is a special case nothing more.

Take the example of a tar archive which has a windows .exe and say
a Linux binary of the same name excluding the .exe. The current behaviour
will have random results depending on the order of the files in the
archive. So its likely that even though the archive extracted a working
.exe file once the extract is actually complete the .exe will not be
present.

I appreciate that the idea was to make cygwin more internally consistent
however surely predictable vs. random behaviour (as far as the user
is concerned) is preferable is it not?
