It isn't possible to include files using line numbers, as of now.
Here's a quick patch that would add this feature. I have tested it
with small files and works fine. Can somebody tell me if it looks
good?
:lines "5-10" will include the lines from 5 to 10, 10 excluded.
:lines "-10" will include the lines from 1 to 10, 10 excluded.
:lines "5-" will include the lines from 1 to the end of the file.
HTH,
