improve theme shell

passion.zsh-theme: line#106 local cmd="${$(fc -l | tail -1)#* }"

will return line number, and I think it's should be optimized

add -n flag to fc command to ignore the line number.

local cmd="${$(fc -ln | tail -1)#* }"

I found fc can -number to get last so just local cmd="$(fc -ln -1)"; 93e68a3eb714e361719e0ffce25c4d2108baf475
