Add info/dir to arch branch
More build-in-place tweaking of arch tagging
Tweak arch tagging to make build/install-in-place less annoying Previously, autoconf-created Makefiles and the like would contain duplicate taglines (unfortunately, autoconf doesn't seem to have a `strip in generated file' comment mechanism) leading to conflicts, and installing in place would create unknown directories and copies of source directories (leading to conflicts with the source directories). This changeset makes all autoconf-processed files use explicit id-tags and adds .arch-inventory entries to ignore installation directories.
Tweak source regexps so that building in place won't cause problems
