FYI: Eight easy patches

[Stepan Kasal]

Hello,
  I commited eight patches.  They are very simple, so I hope you don't
mind that I packed them in one mail.  Below are the respective changelog
entries.

Have a nice day,
        Stepan

        * lib/autoconf/general.m4 (AC_MSG_CHECKING, AC_MSG_RESULT):
          Put braces around the two echo commands, for consistency
          with AC_MSG_ERROR and such.

        * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
          common code; used in many places in the tree.

        * lib/m4sugar/m4sh.m4 (AS_ESCAPE): Make the pattern a bit simpler;
          use \& insetad of \1.

        * lib/m4sugar/m4sh.m4 (_AS_ECHO_UNQUOTED): Move the macro lower;
        no code change.

        * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.

        * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
          messages when ac_unique_file is not found.

        * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Simplify the
          `if' at the end.

        * bin/autoconf.as: Make more use of "shift 2" in option processing.
