=item MY_CXT_CLONE
By default, when a new interpreter is created as a copy of an existing one
-(eg via C<<threads->create()>>), both interpreters share the same physical
+(eg via C<< threads->create() >>), both interpreters share the same physical
my_cxt_t structure. Calling C<MY_CXT_CLONE> (typically via the package's
C<CLONE()> function), causes a byte-for-byte copy of the structure to be
taken, and any future dMY_CXT will cause the copy to be accessed instead.
