When
GIT_MERGE_FIND_RENAMES
is set, provide a default forrename_threshold
when it is unset.The merge machinery expects
rename_threshold
to be nonzero ifGIT_MERGE_FIND_RENAMES
is set. Previously, a consumer could setGIT_MERGE_FIND_RENAMES
but leaverename_threshold
unset and merge would get terribly confused.Fixes #4035
