annotate lib/lib.h @ 543:60b97ba66a70

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Extensive semi-gratuitous refactoring: factor out common code, handle euid!=uid and egid!=gid cases. (Note: test suite requires root access, possibly container support.)
