Revision 2408cff9f738459019709c8c12d0bd8a5605566f authored by Linus Torvalds on 14 July 2005, 00:27:48 UTC, committed by Linus Torvalds on 14 July 2005, 00:27:48 UTC 
Make "git-checkout" create files with O_EXCL
 
We should always have unlinked any old ones before, but this just makes
sure that we never over-write any old file.

A quick "grep" now shows that all the core tools that open files for
writing use O_EXCL, ie we never overwrite an existing file in place.
