Which seems to be largely pointless, since the goal of the function 
is to interact with a specific script.  

If the function doesn't want to detect the shell (ideally, parsing the 
interpreter from the shebang line, perhaps it'd be better just to
name the function(s) something like `source-sh-script' or 
`source-csh-script'.
