Git has various options to ignore whitespace changes during merge:

   ignore-space-change, ignore-all-space, ignore-space-at-eol,
   ignore-cr-at-eol
       Treats lines with the indicated type of whitespace change as
       unchanged for the sake of a three-way merge. Whitespace changes
       mixed with other changes to a line are not ignored. See also
       git-diff(1) -b, -w, --ignore-space-at-eol, and
       --ignore-cr-at-eol.

       •   If their version only introduces whitespace changes to a
           line, our version is used;

       •   If our version introduces whitespace changes but their
           version includes a substantial change, their version is
           used;

       •   Otherwise, the merge proceeds in the usual way.


OTOH, when merging, by design Git never looks at individual commits, it
rather performs 3-way merge with respect to common ancestor, so no
marking of individual commits would help.
