Fix (German?) spelling mistakes in comments: s/save/safe (the adjective)

Might be more of them left, I found these by looking for "is save" or
"it save".

Many more potential misspellings of "Safe" as "Save" in identifiers
are left. Need to check individually which of them actually mean
"Safe", which mean "Saved" perhaps.
