annotate buffer.h @ 958:1bf92da7a2a0

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Try without identifying current user Small change that warns the user if the current user cannot be identified rather than aborting. This came in handy when I put dropbear on a dlink that did not have a true user environment. Falling back on the "-l" option and user@ options works just fine as a client. The only implication I found is that the -J option will fail ungracefully without a known own_user.
