Cygwin's pty's are based on pipes. Therefore, when it interacts with a Win32
program (such as Win32 python), what that program sees is a pipe instead of
a console. This is important because python buffers pipes, and so on a
pty-based terminal, text will not necessarily appear immediately. In most
cases, this isn't a big deal. But when we're doing an interactive prompt,
the result is that the prompts won't display until we fill the buffer. Since
raw_input does not flush the prompt, we need to manually write and flush it.
See https://github.com/mintty/mintty/issues/56 for more details.

Windows has potentially bizarre rules depending on where you look. When
spawning a process via the Windows C runtime the rules are as follows:
https://docs.microsoft.com/en-us/cpp/cpp/parsing-cpp-command-line-arguments
To summarize the relevant bits:
* Only space and tab are valid delimiters
* Double quotes are the only valid quotes
* Backslash is interpreted literally unless it is part of a chain that
leads up to a double quote. Then the backslashes escape the backslashes,
and if there is an odd number the final backslash escapes the quote.

The function first looks for a distribution release file in
/etc and then reverts to _dist_try_harder() in case no
suitable files are found.
supported_dists may be given to define the set of Linux
distributions to look for. It defaults to a list of currently
supported Linux distributions identified by their release file
name.
If full_distribution_name is true (default), the full
distribution read from the OS is returned. Otherwise the short
name taken from supported_dists is used.
Returns a tuple (distname, version, id) which default to the
args given as parameters.
