Doesn't really handle PS1 backslashes

[zinanxing]

I had this in my .bash_profile:

export PS1="\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\]\$ "

And this script failed for this error:

set: Invalid index starting at 'export PS1="\'

~/.config/fish/config.fish (line 23):
	set -xg $var $value
	^
from sourcing file ~/.config/fish/config.fish
	called during startup
