In 80r, which line is that?

Overline aside, I think that what Wladimir posted is an important observation on how q is actually composed. It is, actually, a combination of a vertical (with a short ascender) and a c-like shape with a long horizontal tail. This is clearly seen in e.g. f80r, line 11, vor 2 (qokey), where the two components are disjoint, because the scribe was in a hurry, or in line 2 (qotain) where the ascender is at an angle different from what the c-shape follows.

Next, the gallows such as t or p can be decomposed into the following: vertical + c-shape + tail modifier. The c-shape is apparently the same as in q, only one of the two tail modifiers is appended to it. The vertical, however, is different from that used in q. Here it does not have an ascender, and also it does not tend to slightly bend clockwise which is seen in many q's.

The vertical in q is close to one that is also seen in extended EVA &131; or &204; wherein it goes with a horizontal (appended or prepended, respectively). Note the characteristic slight bend clockwise. Although the short ascender is absent here.
