Fix AC_CONFIG_SUBDIRS tracing in autoreconf.

Browse Source 
* bin/autoreconf.in (autoreconf_current_directory): Collapse
newlines in the autoconf trace output, similar to how automake
invokes autoconf, so that newlines do not matter in the argument
to AC_CONFIG_SUBDIRS.
* tests/torture.at (Deep Package): Expose this issue in the
test.
* THANKS: Update.
