  cosmetics: better use of m4 quoting and m4sugar macros
  
  * m4/dmalloc.m4: Better use of m4 quoting.  Bump serial number.
  * m4/gcj.m4: Likewise.
  * m4/init.m4: Likewise.
  * m4/install-sh.m4: Likewise.
  * m4/lex.m4: Likewise.
  * m4/multi.m4: Likewise.
  * m4/option.m4: Likewise.
  * m4/python.m4: Likewise.
  * m4/sanity.m4: Likewise.
  * m4/cond.m4: Likewise.  Also, prefer the m4sugar macro 'm4_if'
  over the plain m4 macro 'ifelse'.
  * m4/depend.m4: Likewise.
