0.11.7 (Sep 06, 2019) -- python2-we-still-love-you-but-...

Primarily bugfixes with some optimizations and refactorings.

 Fixes

- [addurls][]
  - now provides better handling when the URL file isn't in the
    expected format.  ([#3579][])
  - always considered a relative file for the URL file argument as
    relative to the current working directory, which goes against the
    convention used by other commands of taking relative paths as
    relative to the dataset argument.  ([#3582][])

- [run-procedure][]
  - hard coded "python" when formatting the command for non-executable
    procedures ending with ".py".  `sys.executable` is now used.
    ([#3624][])
  - failed if arguments needed more complicated quoting than simply
    surrounding the value with double quotes.  This has been resolved
    for systems that support `shlex.quote`, but note that on Windows
    values are left unquoted. ([#3626][])

- [siblings][] now displays an informative error message if a local
  path is given to `--url` but `--name` isn't specified.  ([#3555][])

- [sshrun][], the command DataLad uses for `GIT_SSH_COMMAND`, didn't
  support all the parameters that Git expects it to.  ([#3616][])

- Fixed a number of Unicode py2-compatibility issues. ([#3597][])

- [download-url][] now will create leading directories of the output path
  if they do not exist ([#3646][])

 Enhancements and new features

- The [annotate-paths][] helper now caches subdatasets it has seen to
  avoid unnecessary calls.  ([#3570][])

- A repeated configuration query has been dropped from the handling of
  `--proc-pre` and `--proc-post`.  ([#3576][])

- Calls to `git annex find` now use `--in=.` instead of the alias
  `--in=here` to take advantage of an optimization that git-annex (as
  of the current release, 7.20190730) applies only to the
  former. ([#3574][])

- [addurls][] now suggests close matches when the URL or file format
  contains an unknown field.  ([#3594][])

- Shared logic used in the setup.py files of Datalad and its
  extensions has been moved to modules in the _datalad_build_support/
  directory.  ([#3600][])

- Get ready for upcoming git-annex dropping support for direct mode
  ([#3631][])
