Today I’m glad to say I found my answer.

Here are two examples:

diff -y <(sort file1) <(sort file2)
comm -3 <(sort file1) <(sort file2)

See this wikipedia entry for a comparison of the diff and comm commands.

I’m not referring to bash, but rather the normal — and thus lame — Windows command box. Things just don’t feel right… some keys don’t work as expected and forget about making the window wider. Fortunately, there is a better way!

Rather, I should say there are better ways: puttycyg and mintty.

puttycyg is a patched version of putty with support for cygwin. mintty is … well, yeah, it’s based on putty, too.

If you use cygwin, you owe it to yourself to try one or both of them immediately. And by that I mean stop reading and start downloading. Now.
