Untrue. Edit /etc/passwd.

Untrue. cygcheck, wish and other programs in the cygwin tree may be
native programs, and cygwin linked programs may reside outside the tree.

Imagine away... Cygwin's path includes the windows directory - and that
means many programs that won't unquote arguments.

How to Disable Automatic Short File Name Generation:

hard to discuss the topic at hand.=20

As a final comment in the vague hope you'll try rather than just arguing
from imagination:
* You should try Chris's list of tests.
* You could ask the list (via the archives or direct) the simplest way
to get rid of the space in your cygwin home directory.=20
