 Parameters are DEATH-MONTH, DEATH-DAY, DEATH-YEAR; the diary
 entry is assumed to be the name of the person.  Although the date
 of death is specified by the civil calendar, the proper Hebrew
 calendar Yahrzeit is determined.
 
+If the death occurred after local sunset on the given civil date,

+death--set the optional parameter AFTER-SUNSET non-nil in this case.

 \(e.g. to DEATH-DAY, DEATH-MONTH, DEATH-YEAR in the European style).

 use when highlighting the day in the calendar."
