Fixed size?

I thought this was OK because the only place that wrote to the cfg in code (cfg_register_fileext) also limited the key size to 15. However, this doesn't take into account manual editing of the config file

Yes, for the fileext it might apply, but not for other keys. Part of this effort of refactoring this is to make the code more versatile, isn't it? :-)

How would one make this a non-static size? A variable and a helper function?

Most likely, yes. Alternatively make the fixed size bigger and provide it as a global constant.

// don't write to value_sz or value; instead, use cfg_set_value
size_t value_sz;
char *value;
};

void cfg_open(void);
void cfg_open_file(const char *filepath);
void cfg_close(void);
char *cfg_get(const char *key);
// get/put only work if cfg file is open
