Many thanks to Pete and Herb.
This opens new questions :
-- What is the default ? With or without --shell-escape ?
-- When a user changes Texshop preferences, are the preferences
changed for that user only, or for everybody ? (I could look by
myself, but the answer may be of use to some people.)
-- How did you come to know the meaning of "\write18", and that for
Texshop it corresponds to "--shell-escape" ? By knowing well the TeX
Book and Unix ? By other means ? I cannot get used to the idea that
typing in TeX is like doing mathematics: you need to learn advanced
calculus, higher algebra, topology, projective geometry and
analytical functions only to understand the meaning of a correct
statement about points of algebraic curves which be valid for every
point (singular points as well).
