git: problems in read-only trees

Dear diary, on Wed, Aug 03, 2005 at 09:42:41AM CEST, I got a letter
where Wolfgang Denk [off-list ref] told me that...

Hello,

sometimes I have to  work  in  trees  for  which  I  have  only  read
permissions; cogito has problems then - for example:

-> cg-diff 
fatal: unable to create new cachefile
fatal: unable to create temp-file

It would be nice if there was at least a way to specify  some  TMPDIR
instead of the current directory in such a situation.

This is a bug in git-diff-* (producing the second error message; the first
error message means failed git-update-cache --refresh but that isn't
fatal). Any reason why prep_temp_blob() works in . instead of $TMPDIR?
