Cannot use `Declare` INI setting to declare empty string #430

Open c-lipka opened 3 years ago

c-lipka commented 3 years ago

When using the (undocumented) string form of the Declare INI setting (using e.g. Declare='Foo=""'), the variable in question will be defined as ", rather than an empty string.

On Ubuntu 20.04 found this to be true of both the ini and command line declare settings. Aside: The parsing code is somewhat different between the command line and ini declare approaches.
