patch: Protect tcsh init scripts against home dirs with spaces in them

[Jeremy Elson]

Hi,
I'm not sure if this is a cygwin bug or an upstream bug, but I've
found a bug in the latest
cygwin 1.7 beta that prevents tcsh from initializing correctly in home
directories with spaces
in them.  A Windows username with a space (e.g., "John Doe") produces
a home directory
with a space, so this is a pretty common case.

The patch below uses double-quotes to protect a filename with a space
from becoming two
arguments in /etc/profile.d/complete.tcsh.  Most of that script is
already similarly protected
but this one was overlooked.  Starting tcsh without this patch on a
home directory that
contains a space just generates an error of "if: Expression syntax",
and the rest of the init
scripts fail.

Thanks,
Jeremy Elson
