Subject: [PATCH] For PR automake/450: * aclocal.in (write_aclocal,
 trace_used_macros): Do not add/remove acinclude.m4 and configure.ac to the
 include map in these two places ... (strip_redundant_includes): ... do it
 here.  This completes the previous change from 2005-03-01, that did not
 update write_aclocal. * tests/acloca19.test: Augment. Report from Peter
 Breitenlohner.
