I agree. I prefer arch to give me back the same file I gave it. And 
layer on top of that the semantics. For instance, it would be possible 
to have a pre-commit hook that would go into the newly formed ,,commit 
directory, and change all the .patch files to remove CR/LF, and have a 
post update/get script that would add CR/LF back. You just have to take 
a lot of care to only do the correct files.

That's why the precommit hook script just refuses to commit if a file 
endings are not what it likes. You can always change it's mind, or you 
can go run dos2unix/unix2dos/whatever to make it run correctly.

Is this good for anyone who runs tla? Probably not, but for people like 
me, it's really what I prefer. I like being in control, and knowing that 
arch won't mess with my files. What I give it is what I get back.

I guess I've just been bitten by someone checking a CR/LF file in unix 
mode, and then the checkout has all CR/LF/LF, not pretty.

That, or someone forgets to set the binary flag, and checks in a .png 
file. Again, not something that comes out correct on the other side.
