Describe the bug

autocomplete not works after source, only works after login.

To reproduce

setup autocomplete according to the document:

• copy file go/pkg/mod/github.com/urfave/cli/[email protected]/autocomplete/bash_autocomplete to ${HOME}/.bash_completion.d/xdc.sh
• add 2 lines at the end of file .bashrc:

PROG=XDC
source ${HOME}/.bash_completion.d/xdc.sh

Then run command source .bashrc, but autocomplete does not work at this time. It does not work either after I run the above commands in terminal directly. But autocomplete works after I logout and login.

Expected behavior

autocomplete works after source, no need to relogin.
