v9:
-* Support DEB_BUILD_OPTIONS=debug ; maybe also support passing
- -g -O2 by default. See patch (and discussion of why this breaks
- compatability) in #544844.
* escaping in config files (for whitespace)?
* dh_installinit --restart-after-upgrade as default?
* delsubstvar() and the last parameter to addsubstvar that makes it remove
a string are not used in debhelper itself, but have been left in the
library in case other things use them. Deprecate and remove.
-* dh --before , --after , --until , --remaining (not formally deprecated yet)
+* dh --before , --after , --until , --remaining
* debian/compress files
* deprecate dh_gconf for dh_installgsettings (stuff should be migrating
away from gconf, and then I can just remove it -- have not added warning
