Re: git log --name-only improvement: show old file name in rename

[Nathan Faulkner <natedogith1@gmail.com>]

The documentation for --name-only says "Show only names of changed 
files." I would interpret this to mean "output the names of all files 
that changed", not "output the names of all files that changed, unless 
git detected it as renamed".  --no-renames makes it behave as expected, 
but having to specify it isn't obvious.  A warning in the documentation 
could help, but --no-renames should probably be included by default when 
--name-only is specified.

I ran into an issue today with code that expected git diff --name-only 
to output all changed files.  A file was created and an unrelated file 
was deleted in the same commit, but they happened to be similar enough 
that git detected it as rename, and thus git diff --name-only indicated 
only one file changed when two files were actually changed.
