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.
