Excerpt from patch:

+AC_CHECK_PROGS(AWK, [gawk, awk, mawk, nawk])
+AC_CHECK_PROGS(AWK, gawk awk mawk nawk)

I noticed several places in the patch for autoconf.texi where inconsistent  
quoting is used, such as in the above example.  Since proper quoting is now  
the recommended Autoconf "way", I would have expected the examples to quote  
both arguments, rather than just one or neither.  For instance:

AC_CHECK_PROGS([AWK], [gawk, awk, mawk, nawk])
AC_CHECK_PROGS([AWK], [gawk awk mawk nawk])

Was the inconsistent quoting just a simple oversight?
