Treat untitled buffers as scratch buffers.
Scratch buffers persist between sessions (e.g. closing and re-opening Textadept will re-open
any scratch buffers) unless Textadept is in "no session" mode (the -n or --no-session
flag was passed).
Install this module by copying it into your ~/.textadept/modules/ directory or Textadept's modules/ directory, and then putting the following in your ~/.textadept/init.lua:
require('scratch')
The directory to temporarily save scratch files to. The default value is ~/.textadept/scratch/.
