bookmarks: Avoid unconditional forwarding of bookmarks for the null revision This patch fixes the following minor problem: % hg bookmark -r null test % hg bookmarks test -1:000000000000 [...] % hg commit % hg bookmarks * test 17:861ce7a241f9 That is: Bookmarks referring to the null revision are always forwarded to the current revision.

bookmarks: Rename --move to --rename To me, --move sounds like "make an existing bookmark refer to another revision", but --move currently means "rename an existing bookmark". This patch renames the switch to --rename to make it easier to understand.
