  m4: do not quote `like this', as per GCS recommendation
  
  This patch converts the files comprising the automake's own build
  system to the use of new quoting format 'like this' or "like this"
  rather than `like this'.
  
  * m4/auxdir.m4, m4/ccstdc.m4, m4/depend.m4, m4/depout.m4, m4/tar.m4,
  m4/init.m4, m4/maintainer.m4, m4/make.m4, m4/missing.m4, m4/vala.m4,
  m4/mkdirp.m4, m4/sanity.m4, m4/silent.m4, m4/strip.m4: Update and
  adjust quoting format throughout, in comments and diagnostic.  Some
  minor related rewordings and reformatting since we are at it.  Bump
  serial numbers.
