[Github-comments] [geany/geany] [devel] Improving utils_free_pointers() (#2288)

[Nick Treleaven]

`utils_free_pointers()` has a clear name, but requires a leading count of pointers, which could be too big or too small, and a trailing NULL, to try to detect if the count is too big.

I realized now we require C99, we can solve all these issues with a macro:
```c
#define FREE_EACH(...) do { \
    void *_arr[] = {__VA_ARGS__}; \
    for (guint _i = 0; _i < G_N_ELEMENTS(_arr); _i++) \
        g_free(_arr[_i]); \
    } while (0)
```
Shall I make a PR?
