however the double backslash _is_ special in that in prevents the 2nd backslash from escaping the following character. the reason for this is to allow shlex to consume the double backslash during command splitting.
for less surprises, stick to shlex POSIX mode, regardless of the running platform. on win32 platforms, explicitly convert a single backslash to double backslash, unless the following character is "special" fix tox-dev#2635 str_convert fixup str_convert: always use shlex POSIX mode for less surprises, stick to shlex POSIX mode, regardless of the running platform. on win32 platforms, explicitly convert a single backslash to double backslash, unless the following character is "special" fix tox-dev#2635 str_convert fixup

Add a note that backslashes remaining in the string after substitution will be handled by shlex, noting platform-specific difference.

When parsing command lines, use
shlex(..., posix=True), even on windows platforms, since non-POSIX mode does not handle escape characters and quoting like a shell would. This improves cross-platform configurations without hacks or esoteric quoting.To make this transition easier, on Windows, the backslash path separator will not treated as an escape character unless it preceeds a quote, whitespace, or another backslash chracter. This allows paths to mostly be written in single or double backslash style.
Note that double-backslash will no longer be escaped to a single backslash in substitutions, instead the double backslash will be consumed as part of command splitting, on either posix or windows platforms.
In some instances superfluous double or single quote characters may be stripped from arg arrays in ways that do not occur in the default windows
cmd.exeshell.TODO
Ensure this does not regress #2732 and other recent fixes around the substitution parser.
