# The string is quoted in python style, which isn't the same as quoting in zsh.
# For example, the literal 'foo"\'bar' denotes foo"'bar in python but in zsh
# it is malformed.
#
# We cheat a bit and impelement not exactly correct unquoting. It may produce
# different visual results but won't perform unintended expansions or bleed out
# any escape sequences.
#
# Note that venv performs unusual and obviously unintended expansions on the
# value of `prompt`: single-word expansions are performed twice by `activate`,
# and then again on every prompt if `prompt_subst` is in effect. While in general
# I am OK with being bug-compatible with other software, the bugs in venv are a
# bit too extreme for my comfort. I am going to disable all expansions and
# display the configured prompt literally.
