[TxMt] Changing cursor position from command

[Kevin Cox]

Wow, thanks, Allan!

One minor modifcation to the regular expression:

#!/usr/bin/env ruby
require "#{ENV['TM_SUPPORT_PATH']}/lib/escape.rb"

line = STDIN.read

if line =~ /\A.*(;|{)\Z/
  caret = ENV['TM_LINE_INDEX'].to_i
  print e_sn(line[0...caret]) + ';${0}' + e_sn(line[caret..-1])
else
  print e_sn(line) + ';'
end

This prevents it from putting a semicolon at the end of a line after
an open {. Helps with for loops, for instance.

It's pretty clear I'm not a ruby programmer, eh?
