[PATCH] make it more obvious that temporary files are temporary files

[PATCH] make it more obvious that temporary files are temporary files

[Nicolas Pitre]

When some operations are interrupted (or "die()'d" or crashed) then the 
partial object/pack/index file may remain around.  Make it more obvious 
in their name that those files are temporary stuff and can be cleaned up 
if no operation is in progress.
