[Bash-completion-devel] How to let bash not expand a environment variable when doing command completion?

[Peng Yu]

I was told by people on bug-bash at gnu.org. That I should send the
following question to bash-completion. Therefore, I sent it to this
mailing list.

==================

When I type 'cd $HOME/.<TAB>', bash will expand the command to 'cd
/home/my_user_name/.'. Would you please let me know how to let bash not
expand the environment variable?
