ここでは [CODE(HTMLe)@en[[[tab]]]] は [[Netscape]]
拡張とされています。が、 [CODE(HTMLe)@en[[[tab]]]]
が [[Netscape Navigator]] で実装されたことなどあったでしょうか?

>Underlines, overlines and strike-through lines are applied to letters and also to spaces between words, even when those spaces are stretched as a result of line justification. Spaces that are the result of tabs (<TAB> in HTML) do not get lines. The visually best position of the lines can often be found in the meta-information of a font. If the font has no such parameters, the application should use some heuristics.
