fileset: fix generator vs list bug in fast path $ hg debugfileset 'a or b' would only return a or b but not both because the base file list was a generator instead of a replayable sequence.

debugfileset: implement --rev, more tests

test-fileset: test remaining predicates - exec - symlink - size - resolved / unresolved - subrepo

fileset: do not traceback on invalid grep pattern

fileset: matchctx.existing() must consider ignored files When running: $ hg debugfileset 'binary() and ignored()' getfileset() was correctly retrieving ignored files but matchctx.existing() was not taking them in account. Just add them along with unknown files.

fileset: matchctx.existing() must consider unknown files By default, unknown files are ignored. If the 'unknown()' predicate appears in the syntax tree, then they are taken in account. Unfortunately, matchctx.existing() was filtering against non-deleted context files, which does not include unknown files. So: $ hg debugfileset 'binary() and unknown()' would not return existing binary unknown files.

fileset: exclude deleted files from matchctx.existing() Running: $ hg debugfileset 'binary()' would traceback if there were one deleted file in the working directory. It happened because matchctx.existing() was filtering files against the ctx.__contains__() but deleted files are still considered part of workingctx.
