Open MacVim tabs from command-line

Change the mvim script as follows to open files in new tabs instead of new windows when starting MacVim from the command line:

1. Add the following line to the top of the file, below the commented section:

   tabs=true

   
   
2. Replace the if structure at the bottom of the file with the following:
   

   # Last step:  fire up vim.
   if [ "$gui" ]; then
   if $tabs && [[ `$binary --serverlist` = "VIM" ]]; then
     exec "$binary" -g $opts --remote-tab-silent ${1:+"$@"}
   else
     exec "$binary" -g $opts ${1:+"$@"}
   fi
   else
   exec "$binary" $opts ${1:+"$@"}
   fi
