HOME dir depends on entries in:

	/etc/nsswitch.conf

whether you have /etc/passwd and/or /etc/group files and their entries;

your SAM and/or AD entry contents including e.g.

	$ net user $USER | grep '^Comment'
	Comment		<cygwin home="/home/..." group="Users"...>

You can check if any of these are in effect by running:

	$ getent passwd $USER

If you think they are relevant, you might also want to try to trace and debug
your bash-completion setup scripts:

	$ set -vx
	$ . /etc/profile.d/bash_completion.sh |& tee /tmp/completion.log | less

to see what they are doing that might affect other settings.
