graphlog: remove useless check for empty repo when --follow is specified
This prepares for extracting common part from getgraphlogrevs() and
getlogrevs(). getlogrevs() does not handle empty repo specially.
When it was added at
d74099ac2ac1, revs were build by old-style query, '.:0'.
So I think the purpose of "len(repo) > 0" was to handle the case of . = null.
Currently it isn't necessary for 'reverse(:.)', and it does not work if repo
is not empty but p1 is null.
$ hg up null
$ hg glog --follow -T '{rev}:{node|short}\n'
o 0:
0a04b987be5a
The subsequent patch will fix this problem, so drops the wrong version for now.
