Sorry for submitting the wrong patch.
Recently, when I checked the sdcv source code, I found that this environment
variable does not support multiple paths and is separated by colons.
```
const gchar *stardict_data_dir = g_getenv("STARDICT_DATA_DIR");
std::string data_dir;
if (!opt_data_dir) {
if (!only_data_dir) {
if (stardict_data_dir)
data_dir = stardict_data_dir;
else
data_dir = "/usr/share/stardict/dic";
}
} else {
data_dir = get_impl(opt_data_dir);
}
```
