[svn-r13168] Purpose:

Browse Source 
bug fix.

Problem:
1. The last fix using "svn --version" did not work since the source code
is shared between different machines which have different svn versions.
Changed the code to inspect the .svn/entries content to guess what version
of svn uses.  From that to decide which GETSVNENTRIES to use.

2. GETSVNENTRIES_14 had two errors:
2.a., % as 1,$ is actually not recognized by ed.  Changed that to "1,$s/..."
  but that got mixed up with $ being a shell meta-character.  Changed to use
  g command instead. (Could have use \ to escape $ but g is cleaner.)
2.b., Some directories have no files but sub-directories.  The ed script
  might end up with an empty file in some steps and ed does not like to
  run g command with an empty file.  Fixed it by adding a dummy blank line.

Platforms tested:
Osage and copper.
