Say whether the document gave a width, or whether it did not - #2

One of the fourteen standard faces is written with no widths at all — every reader is expected to know Times and Helvetica and Courier by heart. A reader that draws a stand-in for such a font has to take the advances from the stand-in too, and it cannot do that without knowing which widths were the document's own. Half an em for every letter reads as a typewriter, which is not what the page says.

One of the fourteen standard faces is written with no widths at all — every reader is expected to know Times and Helvetica and Courier by heart. Of 113 140 unembedded fonts in the corpus, 39 431 are written that way.

Widthreturns half an em for a code the document did not mention, and half an em for every letter reads as a typewriter — which is not what the page says.HasWidthtells the two apart.100% statement coverage.
