so, basically you are looking for a way of putting #!/bin/bash before the 
output of fc is included?

I don't see any obvious ways of doing this, but, you could, if you wanted to, 
use .bash_history (or the appropriate history-file for your shell) and grep 
for what you want there?

When you set emacs to be the editor, remember that you call emacs with a new 
file as argument, i.e. if you specify foo as a file, emacs will open *both* 
foo and the new file from fc. 

You could, perhaps, add a hook in .emacs as all files created by fc starts 
with [shell]-fc-<numbers>

so basically, I think the question boils down to:

"""
How do I create a hook in my .emacs so that all files starting with bash-fc-* 
will load sh-mode?
