All tracked files should be taken from <branch> and all non-zero stages removed. Most of this is true, except that the final file could be in stage one instead of zero. "checkout -f" (among other commands) does this with one-way merge, which is supposed to take stat info from the index and everything else from the given tree. The add_entry(.., old, ...) call in oneway_merge() though will keep stage index from the index. This is normally not a problem if the entry from the index is normal (stage #0). But if there is a conflict, stage #0 does not exist and we'll get stage #1 entry as "old" variable, which gets recorded in the final index. Fix it by clearing stage mask. This bug probably comes from `b5b425074e` (git-read-tree: make one-way merge also honor the "update" flag, 2005-06-07). Before this commit, we may create the final ("dst") index entry from the one in index, but we do clear CE_STAGEMASK. I briefly checked two- and three-way merge functions. I think we don't have the same problem in those.

unpack-trees: fix oneway_merge accidentally carry over stage index

Phillip found out that 'git checkout -f <branch>' does not restore
conflict/unmerged files correctly. All tracked files should be taken
from <branch> and all non-zero stages removed. Most of this is true,
except that the final file could be in stage one instead of zero.

"checkout -f" (among other commands) does this with one-way merge, which
is supposed to take stat info from the index and everything else from
the given tree. The add_entry(.., old, ...) call in oneway_merge()
though will keep stage index from the index.

This is normally not a problem if the entry from the index is
normal (stage #0). But if there is a conflict, stage #0 does not exist
and we'll get stage #1 entry as "old" variable, which gets recorded in
the final index. Fix it by clearing stage mask.

This bug probably comes from b5b425074e (git-read-tree: make one-way
merge also honor the "update" flag, 2005-06-07). Before this commit, we
may create the final ("dst") index entry from the one in index, but we
do clear CE_STAGEMASK.

I briefly checked two- and three-way merge functions. I think we don't
have the same problem in those.

t/t2023-checkout-m.sh: fix use of test_must_fail

Change an invocation of test_must_fail() to be inside a
test_expect_success() as is our usual pattern. Having it outside
caused our tests to fail under prove(1) since we wouldn't print a
newline before TAP output:

    CONFLICT (content): Merge conflict in both.txt
    # GETTEXT POISON #ok 2 - -m restores 2-way conflicted+resolved file
