pullreport: issue a message about "extinct" pulled changesets
Changeset pulled from a remote repository while already obsolete locally can
end up hidden after the pull. Hiding obsolete changesets is a good behavior
but silently "skipping" some of the pulled content can get confusing.
We now detect this situation and emit a message about it. The message is
simple and the wording could be improved, however, we focus on the detection
here. Evolution is still an experimental feature, so the output is open to
changes.
In particular, we could point out at the latest successors of the obsolete
changesets, however, it can get tricky is there are many of them. So we delay
these improvements to another adventure.
Another easy improvement would be to merge this message with the previous line
about the new nodes and their phases.
This is a good example of cases where we can only transmit a limited amount of
data to users by default. We need some sort of "transaction journal" we could
point the user to.

Mercurial supports a functional language for selecting a set of files. Like other file patterns, this pattern type is indicated by a prefix, 'set:'. The language supports a number of predicates which are joined by infix operators. Parenthesis can be used for grouping. Identifiers such as filenames or patterns must be quoted with single or double quotes if they contain characters outside of ``[.*{}[]?/\_a-zA-Z0-9\x80-\xff]`` or if they match one of the predefined predicates. This generally applies to file patterns other than globs and arguments for predicates. Pattern prefixes such as ``path:`` may be specified without quoting. Special characters can be used in quoted identifiers by escaping them, e.g., ``\n`` is interpreted as a newline. To prevent them from being interpreted, strings can be prefixed with ``r``, e.g. ``r'...'``. See also :hg:`help patterns`. Operators ========= There is a single prefix operator: ``not x`` Files not in x. Short form is ``! x``. These are the supported infix operators: ``x and y`` The intersection of files in x and y. Short form is ``x & y``. ``x or y`` The union of files in x and y. There are two alternative short forms: ``x | y`` and ``x + y``. ``x - y`` Files in x but not in y. Predicates ========== The following predicates are supported: .. predicatesmarker Examples ======== Some sample queries: - Show status of files that appear to be binary in the working directory:: hg status -A "set:binary()" - Forget files that are in .hgignore but are already tracked:: hg forget "set:hgignore() and not ignored()" - Find text files that contain a string:: hg files "set:grep(magic) and not binary()" - Find C files in a non-standard encoding:: hg files "set:**.c and not encoding('UTF-8')" - Revert copies of large binary files:: hg revert "set:copied() and binary() and size('>1M')" - Revert files that were added to the working directory:: hg revert "set:revs('wdir()', added())" - Remove files listed in foo.lst that contain the letter a or b:: hg remove "set: listfile:foo.lst and (**a* or **b*)"
