filectx: add isabsent method...
filectx: add isabsent method This will indicate whether this filectx represents a file that is *not* in a changectx. This will be used by merge and filemerge code to know about when a conflict is a change/delete conflict. While this is kind of hacky, it is the least bad of all the alternatives. Other options considered but rejected include: - isinstance(fctx, ...) -- not very Pythonic, doesn't support duck typing - fctx.size() is None -- the 'size()' call on workingfilectxes causes a disk stat - fctx.filenode() == nullid -- the semantics around filenode are incredibly confusing. In particular, for workingfilectxes, filenode() is always None no matter whether the file is present on disk or in either parent. Having different behavior for None versus nullid in the merge code is just asking for pain. Thanks to Pierre-Yves David for early review feedback here.

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.
