manifest: for diff(), only iterate over files, not flags From manifest.diff(), we return a dict from filename to pairs of pairs of file nodeids and flags (values of the form ((n1,n2),(fl1,fl2))). To create this dict, we currently generate one dict for files (with (n1,n2) values) and one for flags (with (fl1,fl2) values) and then join these dicts. Missing files are represented by None and missing flags by '', but due to the dict joining, the inner pairs themselves can also be None. The only caller, merge.manifestmerge(), then unpacks these values while checking for None values. By inlining the calls to dicthelpers and simplifying it to only iterate over files (ignoring flags-only differences), we can simplify life for our caller.

Mercurial supports several ways to specify individual revisions.
A plain integer is treated as a revision number. Negative integers are
treated as sequential offsets from the tip, with -1 denoting the tip,
-2 denoting the revision prior to the tip, and so forth.
A 40-digit hexadecimal string is treated as a unique revision
identifier.
A hexadecimal string less than 40 characters long is treated as a
unique revision identifier and is referred to as a short-form
identifier. A short-form identifier is only valid if it is the prefix
of exactly one full-length identifier.
Any other string is treated as a bookmark, tag, or branch name. A
bookmark is a movable pointer to a revision. A tag is a permanent name
associated with a revision. A branch name denotes the tipmost open branch head
of that branch - or if they are all closed, the tipmost closed head of the
branch. Bookmark, tag, and branch names must not contain the ":" character.
The reserved name "tip" always identifies the most recent revision.
The reserved name "null" indicates the null revision. This is the
revision of an empty repository, and the parent of revision 0.
The reserved name "." indicates the working directory parent. If no
working directory is checked out, it is equivalent to null. If an
uncommitted merge is in progress, "." is the revision of the first
parent.
