- version bump
- Sort rm commands output for mostlyclean-generic, clean-generic,
distclean-generic and maintainer-clean-generic, so that the produced
Makefile is not sensitive to the way Perl sorts its hashes.
- Support `+' in the name of directories given to `include'.
- Preserve spaces in the arguments of `compile'.
- `missing' will no longer try to emulate a tool that is run with
`--version' or `--help' as argument.
- There is a new chapter about the history of Automake.
