fixed <prefix>+e not working when EDITOR is set to 'emacsclient -t' and the default shell is zsh (2), fixes #593

${EDITOR//gvim/vim} and ${EDITOR//mvim/vim} have been introduced to fix #416,
however the replace all substitution is not POSIX and is not supported by termux
or dash

the proper fix for #416 is to set EDITOR to 'gvim -f' or 'mvim -f'
