[Bug 1948340] [NEW] bash-completion breaks with environment Variables

[Mark Jones]

Public bug reported:

Why does:

    vi $VIRTUAL_ENV/bin/postact<TAB>

become

    vi \$VIRTUAL_ENV/bin/postactactivate

on ubuntu 20.04 and

    vi $VIRTUAL_ENV/bin/postactactivate

on macOS.  The Ubuntu version ruins autocomplete for this command.


macOS$ echo $BASH_VERSION
3.2.57(1)-release

ubuntu$ echo ${BASH_VERSION}
5.0.17(1)-release

Would be nice to be able to use bash-completion without is messing up so
completely with reckless quoting.
