When compiling on Linux with GCC 13 and `-Wincompatible-pointer-types`:

``` prjorg-sidebar.c: In function 'prjorg_sidebar_get_expanded_paths': prjorg-sidebar.c:1565:16: warning: returning 'void **' from a function with incompatible return type 'gchar **' {aka 'char **'} [-Wincompatible-pointer-types[https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wincompatible-...]] 1565 | return g_ptr_array_free(expanded_paths, FALSE); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ```

Apparently this will become an error by default with GCC 14 in 2024:
