Regexps to match multiple SPACEs after TAB that should be visualized.

The SPACE and TAB characters will be visualized if there at least as many SPACEs as tab-width after a TAB. The value should be a cons whose car is used for SPACEs visualization and whose cdr is used for TABs visualization.

The SPACE characters are highlighted using the whitespace-space-after-tab face. This variable is used when whitespace-style includes space-after-tab, space-after-tab::tab or space-after-tab::space.
