Extra Lines "ENTER"s get rejected

[rogerprz]

When I click multiple spaces (Enter) they are removed by the autosave. Need to place a # for comment or move something else.

I have the same case. I like to add blank lines before starting new contents. If I don't type anything after hitting "Enter" a couple times, the cursor bounces back to the end of the file.

I have the same problem. However:
The reason for this behaviour lies NOT within autosave-onchange's sourcecode but in the atom default saving behavior!

You can verify this by:

1. disabling or deleting 'autosave-onchange' and
2. inserting a few empty lines at the end of your document
3. use hotkey to save (default: 'ctrl + s')

You will notice that the empty lines at the document end are being erased.

The package responsible is the 'whitespace' package in the atom core/default packages.
To disable this behavior and keep all newlines at the end of the file:

uncheck: Settings > Packages > whitespace > Settings: "Ensure Single Trailing Newline"

Now all newlines will remain at the end of all files.
Note that you can also define this feature language-specific - see settings hint for more details.
