workingctx: use member variables to store ignored and clean If some code tries to query ignored or clean files without first calling the explicit status() method to query them, it will raise an exception (indicating a software bug).

workingctx: add explicit status method, add ignored and fix clean workingctx.clean() and memctx.clean() have both been returning ignored files since their creation. This patch fixes clean() while introducing a method for querying ignored files. The new status() method can be used to explicitly override the default (fast) arguments used by the _status property.

context: add a changectx.diff() convenience function With this function, extracting diffs becomes trivial: repo = hg.repository(ui.ui(), path=root) ctx = repo['tip'] for out in ctx.diff(): print out

keyword: omit setting extra variable for record context Since dc2f37864348 the context is always retrieved in kwtemplater.overwrite().
