annotate rogue3/save.c @ 294:fe6b7a1a6dfc

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Improve the documentation build process. The choice between troff implementations is now made at configure time, rather than using shell logic in the Makefile to choose while building.
