largefiles: omit redundant isstandin() before splitstandin() There are many isstandin() invocations before splitstandin(). The former examines whether specified path starts with ".hglf/". The latter returns after ".hglf/" of specified path if it starts with that prefix, or returns None otherwise. Therefore, value returned by splitstandin() can be used for replacement of preceding isstandin(), and this replacement can omit redundant string comparison after isstandin().

misc: update descriptions about removed file for filectxfn Since 650b5b6e75ed, filectxfn for memctx should return None for removed file instead of raising IOError.

osx: always purge build/mercurial before starting build This prevents stray files from previous builds from polluting newer builds.

osx: use more paranoid quoting in test

osx: install completion scripts using install(1) to avoid umask badness This actually fixes some tests that were showing us umask badness that had been overlooked.

merge with stable

py3: prove `hg {add,addremove,commit} all work We can't do a second commit in a repo yet, because pure-Python bdiff is broken on Python 3. That is probably a good next step.

revsetlang: perform quoting using ui.escapestr instead of repr() This changes one of the doctest results, but I'm pretty sure on inspection that it's an equivalent result.

revsetlang: add docstring with some tests to _quote

revsetlang: move quoting function to not be a closure I'm about to change the implementation here and I'd like to add some doctests, which means this needs to not be hidden inside another function.
