Re: [PATCH v2 3/5] completion: add and use __git_compute_first_level_config_vars_for_section

A silly question (primarily because I do not much use the indirect
reference construct ${!name}).  Does the assignment with printf need
to spell out the long variable name with "_${section}"?  Can it be

    printf -v "$this_section" ...

instead, as we already have the short-hand for it?

No, unfortunately neither "$this_section" nor "${!this_section}"
work, so we must use the long name.

Hmph, this does not match my experiment, though.  What am I doing
wrong?

        bash$ vname=foo
        bash$ foo=bar
        bash$ set | grep foo
        foo=bar
        vname=foo
        bash$ printf -v "$vname" "%d" 1234
        bash$ set | grep foo
        foo=1234
        vname=foo
        bash$ echo $BASH_VERSION
