Florian Pritz 9efd10cd2a fix vim syntax highlighting of .sh files
vim recognises what type of shell script it's dealing with by looking at
the shebang. If detection fails it falls back to sh which doesn't
support some bash features. Adding a normal, possibly broken, shebang
which gets fixed by the Makefile allows vim to detect bash syntax.
