`markdown2 some-path > some-path` screws up, wipes out file #46

Redirecting generated output to the same path as the input *wipes out* the 
input. Bad bad.

As far as I am aware, this is common behavior for just about any application; 
using sed in a similar pattern will also result in trashing the input file.

This isn't a bug in markdown2. The shell processes redirections before the 
given program even runs, so the shell truncates the file before markdown2 has a 
chance to open it.
