New submission from telmich:
When using argparse and the string \$ occurs on the commandline, it is
converted to $. This as definitely wrong and renders argparse useless, if the
input needs to be trusted (i.e. defitinely the same as given into it)'
Example code:
import sys
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('test', nargs='*')
result = parser.parse_args(sys.argv[1:])
print("args = %s" % " ".join(sys.argv))
print("result = %s" % result)
Reproduce problem:
[10:41] bento:~% python3 argparse-test.py ps1 "PS1='[\t]
\[\033[1m\]\h\[\033[0m\]:\w\$ '"
] \[\]\h\[\]:\w\$ '"args = argparse-test.py ps1 PS1='[\t]
\[\033[1m\]\h\[\033[0m\]:\w$ '
result = Namespace(test=['ps1', "PS1='[\\t]
\\[\\033[1m\\]\\h\\[\\033[0m\\]:\\w$ '"])
