Documentation

Regexp or function that defines whitespace sequences for compare-windows.

That command optionally ignores changes in whitespace.

The value of compare-windows-whitespace is normally a regexp, but it can also be a function. The function's job is to categorize any whitespace around (including before) point; it should also advance past any whitespace. The function is called in each window, with point at the current scanning point. It gets one argument, the point where M-x compare-windows (compare-windows) was originally called; it should not look at any text before that point.

If the function returns the same value for both windows, then the whitespace is considered to match, and is skipped.

This variable was added, or its default value changed, in Emacs 24.4.
