Subject: Look for a pre-existing .nogit-tmp directory
X-Git-Url: https://git.cworth.org/git?p=nogit;a=commitdiff_plain;h=cadb0b69b70347408a653048b0c3687399f7650f

Look for a pre-existing .nogit-tmp directory

Just to be extra careful, force the user to clean up any remnant of a
previously-aborted run before we dive in again with potentially
unintended consquences.
