But more seriously, how would a user expect this to interact with 
.gitignore? I know gitignore is about ignoring untracked files, but I 
can't help but feel the two have something in common. But maybe not. I'm 
sick today and my brain is not working very well.

I think that the -x option with regular (not --no-index) diff would be 
a little different.  .gitignore is for "git add" time, while "git diff" 
happily ignores .gitignore.

Besides, the -x option only works on the basenames (as I implemented it; 
no idea if GNU diff works the same way, but from Michael's patch it looks 
like it does).

Info: (diff.info.gz)diff Options

`-x PATTERN'
`--exclude=PATTERN'
     When comparing directories, ignore files and subdirectories whose
     basenames match PATTERN.  *Note Comparing Directories::.

`-X FILE'
`--exclude-from=FILE'
     When comparing directories, ignore files and subdirectories whose
     basenames match any pattern contained in FILE.  *Note Comparing
     Directories::.
