Minimal cleanup of the COMPATIBILITY section:
* Mention that the list is incomplete.
* Quoting quotes by doubling them is documented in the
Ossanna/Kernighan/Ritter Nroff/Troff User's Manual, Section 7.3.
* Our roff(7) manual documents handling of escape sequences;
besides, we partially support \w and \z now.
* Scaling widths are documented in roff(7) as well, and f is not \f.
* Negative arguments to .sp are handled now.
