* call-seq:
* remote.fetch(refspecs = nil, options = {}) -> hash
*
* Downloads new data from the remote for the given +refspecs+ and updates tips.
*
* You can optionally pass in an alternative list of +refspecs+ to use instead of the fetch
* refspecs already configured for +remote+.
*
* Returns a hash containing statistics for the fetch operation.
*
* The following options can be passed in the +options+ Hash:
*
* :credentials ::
* The credentials to use for the fetch operation. Can be either an instance of one
* of the Rugged::Credentials types, or a proc returning one of the former.
* The proc will be called with the +url+, the +username+ from the url (if applicable) and
* a list of applicable credential types.
*
* :progress ::
* A callback that will be executed with the textual progress received from the remote.
* This is the text send over the progress side-band (ie. the "counting objects" output).
*
* :transfer_progress ::
* A callback that will be executed to report clone progress information. It will be passed
* the amount of +total_objects+, +indexed_objects+, +received_objects+, +local_objects+,
* +total_deltas+, +indexed_deltas+ and +received_bytes+.
*
* :update_tips ::
* A callback that will be executed each time a reference is updated locally. It will be
* passed the +refname+, +old_oid+ and +new_oid+.
*
* :message ::
* The message to insert into the reflogs. Defaults to "fetch".
*
* :signature ::
* The signature to be used for updating the reflogs.
*
* Example:
*
* remote = Rugged::Remote.lookup(@repo, 'origin')
* remote.fetch({
* transfer_progress: lambda { |total_objects, indexed_objects, received_objects, local_objects, total_deltas, indexed_deltas, received_bytes|
* # ...
* }
* })
