Description
Same problem with Python2 and Python3
import subprocess;print(subprocess.check_output(['echo', '--foo="bar"', '--quux="baz"']).decode())
Prints --foo=\bar" --quux="baz" instead of --foo="bar" --quux="baz"
edit: minimal example ['echo', '"']
This breaks some meson builds when perl scripts are called. For example pango with help2man.

Research direction
Start by reproducing the Python subprocess examples, including the minimal ['echo', '"'] case, and compare the output from cygwin executables. Investigate the MSYS2 runtime argument-passing path and verify the fix against the quoted arguments that currently break Meson builds involving Perl, such as pango with help2man.
