Vanished. Well-known problem in ASCII-artist communities.

Follows best current practice to prepare a Ruby program before
including it in the text of an e-mail. Valid for all e-mail programs
running in Emacsen:

1. mark whole program
2. issue 'M-x untabify'
3. mark whole program again
4. issue 'M-x comment-region'

This leaves the program readable while at the same time keeping the
whitespace intact.

Using 'M-x comment-region' makes sure that the whitespace is no
leading one. Some MUAs are known to remove *any* leading whitespace -
not just spaces!

For making the program runnable again 'M-x uncomment-region' is
suficient.
