[issue2485] Revset subtraction does not work as documented

[Jesse Glick]

New submission from Jesse Glick <jesse.glick at oracle.com>:

'hg help revsets' claims that "x - y" means "Changesets in x but not in y."
Yet on http://hg.netbeans.org/core-main/ the command

hg log -r '::eed728104f48 & ! ::6c5b6ed2225e' -M -v

works as expected to find changes made between two daily builds, but

hg log -r '::eed728104f48 - ::6c5b6ed2225e' -M -v

(which seems like it should be a synonym) seems to list all csets in history.
