Description

The output of thefuck --version (something like The Fuck 3.1 using Python 3.5.0):

The Fuck 3.26 using Python 3.6.5

Your shell and its version (bash, zsh, Windows PowerShell, etc.):

zsh 5.2 (x86_64-apple-darwin16.0)

Your system (Debian 7, ArchLinux, Windows, etc.):

ProductName:    Mac OS X
ProductVersion: 10.12.6
BuildVersion:   16G1314

How to reproduce the bug:

Add --enable-experimental-instant-mode to the alias initialization in .zshrc.
Restart terminal or run source ~/.zshrc.

The Fuck completely stops working (i.e. it doesn't show any correction suggestions to any mistakes) and instead shows the following messages whenever I type the fuck command:

[WARN] PS1 doesn't contain user command mark, please ensure that PS1 is not changed after The Fuck alias initialization
No fucks given

The output of The Fuck with THEFUCK_DEBUG=true exported (typically execute export THEFUCK_DEBUG=true in your shell before The Fuck):

Tech stack: pythonshell
Domain: cli
Issue type: bug
Difficulty: 3
Estimated time: 1-3 hours
Activity status: stale
Clarity: clear
Prerequisites: PythonZsh
Newbie friendliness: 60
Research direction: Investigate the experimental instant mode feature's shell integration. Look at the alias function in the zsh initialization script (likely in the repository's shell directory) to understand how the user command mark is set in PS1. Check the condition in the instant mode code that triggers the warning and causes no corrections. The issue likely lies in the detection of the prompt mark after alias initialization.
