Yeah, thanks for all the detail.

What I was/am using this for is in a script for easily viewing/merging
differences in a git repository using vimdiff:
$VIMDIFF -n "$FILE" <(git diff $REV -- "$FILE" | patch -p1 -Rs -o /dev/stdout)
Since the primary use I have for this is with etckeeper, I could
potentially be looking at stuff where I don't want tempfiles, with
sensitive data in them, to keep track of.
That was my original thinking, in any case.
A sect or party is an elegant incognito devised to save a man from
the vexation of thinking.
