PASSWORD_STORE_CHARACTER_SET_NO_SYMBOLS isn't respected

[Marek Howard]

Hello,

I've the following in my ~/.bashrc

  export PASSWORD_STORE_CHARACTER_SET_NO_SYMBOLS="'"'"`'

I want to forbid '"` characters in generated passwords mostly because it screws 
up some generated configuration files. But even with this variable, I can still 
occasionally see " and ' in generated passwords.

Is this a bug or am I doing something wrong?

I'm using `pass generate foobar` to generate passwords.
