#
# 1. Normal file in p1, largefile in p2. Here the largefile is
# detected via its standin file, which will enter the working copy
# with a "get" action. It is not "merge" since the standin is all
# Mercurial is concerned with at this level -- the link to the
# existing normal file is not relevant here.
#
# 2. Largefile in p1, normal file in p2. Here we get a "merge" action
# since the largefile will be present in the working copy and
# different from the normal file in p2. Mercurial therefore
# triggers a merge action.
#
# In both cases, we prompt the user and emit new actions to either
# remove the standin (if the normal file was kept) or to remove the
# normal file and get the standin (if the largefile was kept). The
# default prompt answer is to use the largefile version since it was
# presumably changed on purpose.

# writing the files into the working copy and lfcommands.updatelfiles
# will update the largefiles.
