* src/search.c (Pcompile): Abort in error if -P and multiple patterns
are specified, with an error message explaining the situation.
Fixing this won't be simple; the '\n' characters separating the
patterns cannot just be replaced by '|' to create an alternation as
back-references are assumed to be local to each individual pattern.
