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.

create cvs repository

  $ mkdir cvsrepo
  $ cd cvsrepo
  $ CVSROOT=`pwd`
  $ export CVSROOT
  $ CVS_OPTIONS=-f
  $ export CVS_OPTIONS

Create a new project

  $ mkdir src
  $ cd src
  $ echo "1" > a
  $ echo "1" > b
  $ cvscall import -m "init" src v0 r0 | sort
  $ cd ..
  $ cvscall co src
  cvs checkout: Updating src
  $ cd src

Branch the project

  $ cvscall tag -b BRANCH
  cvs tag: Tagging .
  $ cvscall up -r BRANCH > /dev/null
  cvs update: Updating .

Modify file a, then b, then a

  $ sleep 1
  $ echo "2" > a
  $ cvscall ci -m "mod a"
  cvs commit: Examining .
  $ echo "2" > b
  $ cvscall ci -m "mod b"
  cvs commit: Examining .
  $ sleep 1
  $ echo "3" > a
  $ cvscall ci -m "mod a again"
  cvs commit: Examining .
