[dependabot-preview]

Bumps yapf from 0.27.0 to 0.29.0.

Changelog

Sourced from yapf's changelog.

[0.29.0] 2019-11-28

Added

• Add the --quiet flag to suppress output. The return code is 1 if there are
  changes, similarly to the --diff flag.
• Add the indent_closing_brackets option. This is the same as the
  dedent_closing_brackets option except the brackets are indented the same
  as the previous line.

Changed

• Collect a parameter list into a single object. This allows us to track how a
  parameter list is formatted, keeping state along the way. This helps when
  supporting Python 3 type annotations.
• Catch and report UnicodeDecodeError exceptions.
• Improved description of .yapfignore syntax.

Fixed

• Format subscript lists so that splits are essentially free after a comma.
• Don't add a space between a string and its subscript.
• Extend discovery of '.style.yapf' & 'setup.cfg' files to search the root
  directory as well.
• Make sure we have parameters before we start calculating penalties for
  splitting them.
• Indicate if a class/function is nested to ensure blank lines when needed.
• Fix extra indentation in async-for else statement.
• A parameter list with no elements shouldn't count as exceeding the column
  limit.
• When splitting all comma separated values, don't treat the ending bracket as
  special.
• The "no blank lines between nested classes or functions" knob should only
  apply to the first nested class or function, not all of them.

[0.28.0] 2019-07-11

Added

• New knob SPLIT_ALL_TOP_LEVEL_COMMA_SEPARATED_VALUES is a variation on
  SPLIT_ALL_COMMA_SEPARATED_VALUES in which, if a subexpression with a comma
  fits in its starting line, then the subexpression is not split (thus avoiding
  unnecessary splits).

Changed

• Set INDENT_DICTIONARY_VALUE for Google style.
• Set JOIN_MULTIPLE_LINES = False for Google style.

Fixed

• BLANK_LINE_BEFORE_NESTED_CLASS_OR_DEF=False wasn't honored because the
  number of newlines was erroneously calculated beforehand.
• Lambda expressions shouldn't have an increased split penalty applied to the
  'lambda' keyword. This prevents them from being properly formatted when they're
  arguments to functions.
• A comment with continuation markers (??) shouldn't mess with the lineno count.
• Only emit unformatted if the "disable long line" is at the end of the line.
  Otherwise we could mess up formatting for containers which have them
  interspersed with code.
• Fix a potential race condition by using the correct style for opening a file
  which may not exist.
