How to delete blank lines and lines with only spaces

[jschwartz13@att.net]

I like to get rid of 'screen space wasting ' blank lines.
I was originally manually deleting them.
For great efficiency, Stephen MacDonald from Textpad,
has helped me with the idea of to replace all of them "^\s+\n" with ""
to remove them.
Quite a time saver and made my life a little easier !!!!
