Rugged::Index#update

Add a new entry to the index or update an existing entry in the index.

If passed a +path+ to an existing, readable file relative to the workdir,
creates a new index entry based on this file.

Alternatively, a new index entry can be created by passing a Hash containing
all key/value pairs of an index entry.

Any gitignore rules that might match +path+ (or the +:path+ value of the
entry hash) are ignored.

If the index entry at +path+ (or +:path+) currently contains a merge conflict,
it will no longer be marked as conflicting and the data about the conflict
will be moved into the "resolve undo" (REUC) section of the index.
