Bug#1016919: lintian: bash-term-in-posix-shell false positive for `. "$(dirname "$0")/functions.sh"`

[Gioele Barabucci <gioele@svario.it>]

Package: lintian
Version: 2.115.2

The following script (approved by `shellcheck -s sh`) causes a false 
positive warning `bash-term-in-posix-shell`:

    #!/bin/sh
    . "$(dirname "$0")/functions.sh"
    do_something

I: my-test: bash-term-in-posix-shell '. "$(dirname "$0")/functions.sh"' 
[usr/bin/my-test:2]

Probably the lintian check is misparsing the quotes and the space 
between `dirname` and `"$0"`, leading it to believe that an argument is 
being passed to the sourced script (that would be, in fact, a bashism).

Regards,
