Correction to pdftex-a.pdf

Hello all,
I've been reading various pdfTeX manuals (from the early TUGboat
article in 1997, to various presentation style files pdftex-s.pdf and
the current pdftex-a.pdf on CTAN), and noticed one recurring
inconsistency in the font explanation section.

Using reference [1], in Section 6.1 Map files, Page 12, there is:

"If the fontflags field is not given, pdfTEX treats it as being 4, a
symbolic font."

Problem: 4 is script font, symbolic font is 3 according to Table 3.

Correction: I don't know what pdfTeX does here, but I suspect 3 rather
than 4, if the font is to be treated as symbolic.
