  pm: do not quote `like this', as per GCS recommendation
  
  This patch converts the internal perl modules used by automake and
  aclocal to the use of new quoting format 'like this' or "like this"
  rather than `like this'.
  
  * lib/Automake/ChannelDefs.pm, lib/Automake/Channels.pm,
  lib/Automake/Condition.pm, lib/Automake/Configure_ac.pm,
  lib/Automake/DisjConditions.pm, lib/Automake/FileUtils.pm,
  lib/Automake/General.pm, lib/Automake/Item.pm,
  lib/Automake/Rule.pm, lib/Automake/Getopt.pm,
  lib/Automake/Options.pm, lib/Automake/Struct.pm,
  lib/Automake/VarDef.pm, lib/Automake/Variable.pm,
  lib/Automake/Version.pm, lib/Automake/XFile.pm: Update and
  adjust quoting format throughout, in comments and diagnostic.
  Some minor related rewordings and reformatting since we are
  at it.
