15% \def\@mkboth{\protect\markboth} to make it more robust
16% Dec 5, 1994:
17% version 1.8: corrections for amsbook/amsart: define \@chapapp and (more
18% importantly) use the \chapter/sectionmark definitions from ps@headings if
19% they exist (which should be true for all standard classes).
20% May 31, 1995:
21% version 1.9: The proposed \renewcommand{\headrulewidth}{\iffloatpage...
22% construction in the doc did not work properly with the fancyplain style.

25% \pagestyle{fancy}'s.
26% June 1, 1995:
27% version 1.92: The sequence \pagestyle{fancyplain} \pagestyle{plain}
28% \pagestyle{fancy} would erroneously select the plain version.
