A "hungry delete" swallows up all whitespace when pressed, rather than just one space, tab, or line-feed at a time.
For instance, when you have this (where "|" is the caret):
Pressing delete will get you to this:
But pressing a hungry delete will get you to this:
Which is much more logical, as it's the exact inverse of pressing enter (i.e., pressing enter auto-indents and opens a new line... pressing hungry delete deletes the indent and closes the line).
Should just emphasize here I was talking about hungry BACKSPACE, not to be confused with the Delete key.
