graphlog: fix output when both a limit and a path are provided

Limit was interpreted as absolute, from the topmost revision, without
counting the number of revisions matching a given file.
Which caused "glog -lN file" to show sometimes less than N csets if
the file was not modified in all of the N previous csets.

glog will now match the behavior of log.
