Sure, but the solution to an inverse problem often gives insight into  
the solution of the original problem. In this case, my command gets  
the length of the heading text and spits out that many hyphens; you  
need to get the length of the heading text (n) and spit out (50 - n)  
spaces. Not so different.

This is pretty neat. I don't remember seeing that substitution trick  
in the TM docs and will try to remember it. The snippet can't,  
however, adjust the length of the underline when I go back and change  
the heading text. This ability is a big deal to me because I'm always  
rewriting. (And since I've changed to using Atx-style headers, the  
best way to underline is moot for me now.)
