merge-trees: let caller decide whether to renormalize

jrn · gitster · commit 1bc0ab7cd13a · 2010-08-06T09:20:00.000-07:00
Add a "renormalize" option to struct merge_options so callers can
decide on a case-by-case basis whether the merge is likely to have
overlapped with a change in smudge/clean rules.  The option defaults
to the global merge_renormalize setting for now.

No change in behavior intended.
