I agree.  On occasion it's useful, but more often than not, keeping
the temporaries is more annoying than anything else.  At the time when
I wrote mergetool, it was a pain for me to either do "git ls-files
--stage" and then cut and paste the SHA hash, or to type commands like
"git cat-file blob :1:long/pathname/from/the/top.c" to look one
various staged versions of the file.   

I'd suggest that this is probably worth turning into an option
(-k|--keep-files), and default the answer to deleting the temporaries
before mergetool exits.
