Because it obeys fields, so if you try to highlight a prompt line in a
comint buffer, only part of the line would be highlighted.

The (only, AFAICT) purpose of pulse-momentary-highlight-one-line is to
locate the cursor, so you want to pulse a little rectangle spanning the
entire width of the window.
