+This function is part of an experimental set of pattern conversion functions.
+It creates and initializes a new convert context. If its argument is
+NULL, \fBmalloc()\fP is used to get the necessary memory; otherwise the memory
+allocation function within the general context is used. The result is NULL if
+the memory could not be obtained.
