[issue13238] Add shell command helpers to shutil module

[Nick Coghlan]

Nick Coghlan <ncoghlan at gmail.com> added the comment:

I realised I could use the convert_field() option in the custom formatter to choose between several interpolation quoting options:

  default - str + shutil.quote_ascii_whitespace
  !q - str + shlex.quote
  !u - unquoted (i.e. no conversion, str.format default behaviour)
  !s - str (as usual)
  !r - repr (as usual)

The most recent commit also exposes public APIs for the formatting aspects (shutil.quote_ascii_whitespace, shutil.shell_format, shutil.shell_format_map)
