merge: first part of fix for issue1327

When there are no renames involved, we shortcut to the changeset
ancestor. This resolves most cases.

Note that Mercurial's rename philosophy elsewhere is that a file's
name is signficant and rename data is only consulted when a file of
the same name is absent.

When Mercurial accepts more than one revision, they may be specified
individually, or provided as a topologically continuous range,
separated by the ":" character.

The syntax of range notation is [BEGIN]:[END], where BEGIN and END are
revision identifiers. Both BEGIN and END are optional. If BEGIN is not
specified, it defaults to revision number 0. If END is not specified,
it defaults to the tip. The range ":" thus means "all revisions".

If BEGIN is greater than END, revisions are treated in reverse order.

A range acts as a closed interval. This means that a range of 3:5
gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
