Looking at ~/.bashrc reminded me to look at /etc/bash_completion.  Could
this section of the latter file be the problem?

# start of section containing compspecs that can be handled within bash

# user commands see only users
complete -u su usermod userdel passwd chage write chfn groups slay w

# group commands see only groups
[ -n "$bash205" ] && complete -g groupmod groupdel newgrp 2>/dev/null

"sudo a" won't complete to apt but rather to document beginning with "a"
in the user home directory.

No.  "apt-g" will not complete to "apt-get", "apt-get u" completes to
"apt-get unshorten"!
