Add to difftree / whatchanged table row with "1", "2", ... links to
'commitdiff' view for diff with n-th parent for merge commits, as a
table header. This is visible in 'commit' and 'comitdiff' views. It
is more important for 'commitdiff' view, as in 'commit' view commit
object header has 'diff' links to diff to n-th parent.
To save space links are shown as "n", where "n" is number of a parent,
and not as for example shortened (to 7 characters) sha1 of a parent
commit. To make it easier to doscover what links is for, encompassing
<th> element has 'title' attribute explaining the link.

This is my proposal on how to provide links to diffs to individual
parents in the 'commitdiff' view. This is RFC: please comment if you
like the idea (or not), and what the layout should be, what this
should look like. Should we add those links only for 'commitdiff'
view, for example?
Some complications in creating layout stem from the fact that "|" is
used as separator, instead of using table border, or cell borders to
separate columns. And we use "|" because in most other places we use
only one cell (column) for the whole series of links.
