Previously, if we edited a new bash script then we would have to wipeout the buffer and recreate it to get syntastic to recognise it as a bash script. This is because it parsed out a magic number and cached that - and it trivially fails to find a magic number when you create a new file. So recheck for a magic number if it is currently empty. Also, do a small refactor.
