fileset: use decorator to mark a predicate as "status caller" Before this patch, predicates calling 'matchctx.status()' are listed up by immediate list value in 'getfileset()'. This prevents 3rd party extensions from adding specific predicate calling 'matchctx.status()'. This uses decorator to mark a predicate as "status caller". This can also localize changes for adding (or removing) a "status caller" predicate function in source code.

fileset: use decorator to mark a function as fileset predicate Using decorator can localize changes for adding (or removing) a fileset predicate function in source code. It is also useful to pick predicates up for specific purpose. For example, subsequent patches marks predicates as "call status" or "use existing" via decorator. To avoid (1) redundancy between "predicate name" and (the beginning of) help document, and (2) accidental typo of help document, this patch also makes decorator put predicate declration into the beginning of help.

fileset: treat encoding and eol as the predicate calling _existing Before this patch, predicate function 'encoding' and 'eol' aren't listed up in '_existingcallers', even though they invoke 'existing()'. This causes unexpected failure of these predicate, if there is a (manually) deleted file in the working directory. 8a0513bf030a and 3ce3f2b059a1 seem to overlook putting already existing 'encoding' or newly introduced 'eol' into '_existingcallers'. This patch also changes order of fileset "eol(unix)" output in test, because "existing caller" predicates show "A(dded)" files before "C(lean)" ones.

rebase: mention conflict in documentation instead of merge

rebase: simplify documentation about heads

rebase: simplify documentation about --keep Also include a warning about bookmarks

rebase: simplify documentation about selecting commits to rebase

rebase: simplify documentation about public commits add reference to graft

verify: clean up weird error/warning lists Nested functions in Python are not able to assign to variables in the outer scope without something like the list trick because assignments refer to the inner scope. So, we formerly used a list to give an object to assign into. Now that error and warning are object members, the [0] hack is no longer needed.

diff: clarify comparison as first parent
