The script parsing the *.messages.in files would treat a line starting with '#' as a comment, but not a line starting with '<whitespace>#'. This means that jamming a '#' right in front of the first character of a message definition (as opposed to the beginning of a line) will have no effect and the line will get treated just the same as a non-commented line. Fix this by trimming all white space from the beginning and ending of the line before processing it.

I do not think we need this check here. Since you added comments to test-messages.in and webkit/MessageReceiver-expected.cpp did not change, it is validation enough.
