Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
web: provide diff summary to the changeset page This is the same message displayed at the end of the "diff --stat" command. For example, "9 files changed, 1651 insertions(+), 2 deletions(-)". The webutil.diffstatgen function allows the diffstat data to be lazily calculated only once and then re-used.
