largefiles: replace splitstandin() by isstandin() to omit str creation
If splitstandin()-ed str itself isn't used, isstandin() should be
used instead of it, to omit meaningless str creation.
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: 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.
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.
