I was guessing that was the case. But how about the first question,  
if there is input how does that statement suck it up automatically?  
(Apologies if this is excruciatingly basic; I'm just trying to  
understand how the input gets passed without explicitly doing so.)

Aha, now that I know there's e_sh(), I do understand it. Thanks :)

It looks like it works well for most cases, but I think the more  
lenient regex causes a problem in the case of a latex comment such as  
"%\usepackage" (note no space); in that case, the comment parameter  
is set to "%\" and the backslash ends up causing problems.
