* bin/autoreconf.in (&parse_args): Remove dead options.
Factor some code.
(&autoreconf): Report the directories we enter *and leave*, so
that error messages can be easily located, and use GNU Make
format, so that Emacs' compile mode understands us.
* lib/Autom4te/General.pm (&update_file): Use `verbose' to report
if some file was changed instead of `print'.
* bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
(&parse_args): Remove the dead options.
* tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new

From Oliver Kiddle and Peter Stephenson.
Have M4sh perform minimal shell sanitizing.
