Option "Ignore Significant Whitespace" doesn't make sense

I don't know why anyone would want to IGNORE the SIGNIFICANT whitespace but see the INSIGNIFICANT whitespace.

The three options that would make sense to me are:

• Don't Ignore Whitespace (shows all whitespace changes)
• Ignore Insignificant Whitespace (shows important whitespace changes inside of Strings, etc.; would be language dependent)
• Ignore All Whitespace (shows no whitespace changes)

Those three options would provide a meaningful progression from ignoring to not ignoring.
