format-check: Optimize format-check.sh

Browse Source 
This commit silences the standard output of wget to generate less noise
when using `format-check.sh` as a pre-commit hook.

It also doesn't redownload the file over and over again but only when
changes were detected. Previous behavior was wget creating numbered
versions by multiple downloads, thus it always used the first version
which was download. That is obviously wrong.

It errors out nicely now when the download failed.
