Two line prompt with full path and Git integration that scales nicely

• `fish_prompt

• Prompts for single Fish command in left bottom corner of given application window
• To make benefit of Fish shell autocompletion and history
• Closes after one command is executed
• If command fails, leaves window to inspect error message

For example you want execute git clone [email protected]:dmi3/bin.git in current directory from Double Commander:

• Press Shift F2 and terminal window appears in left bottom corner of Double Commander window
• First you want git and clone to be autocompleted using Fish
• During clone process you want to see git command output to monitor progeress
• If everything is ok, promt will close
• In case of error you will have chance to read error message

• sudo apt-get install fish wmctrl xterm
