annotate Include/tupleobject.h @ 17581:c1937faabb23 2.1

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Added support for optional explanation parameter to the \versionadded macro. Refactored do_cmd_versionadded() and do_cmd_versionchanged() to do most of the work in a helper function, with the do_cmd_*() wrappers just supplying a portion of the replacement text.
