You guys are (quite properly) worried about all the edge cases and I
have probably
confused things by using the reflog when they may be a better way of
doing things.
Perhaps if I describe the problem, there may be a better solution than using the
reflog. I've made a bunch of changes to a repository, a few weeks
later I figure I've
deleted a file I need but am not really sure of its name. So I want to list the
files that I've deleted during the past few weeks. So the aim is to
find the files that
aren't in the current working directory but that are in some commit done since
day X.
Cheers,
Geoff
