Subject: [PATCH] Fix warnings: spell.c: store_aff_word(): Garbage value: RI.

Problem    : Result of operation is garbage or undefined @ 5809.
Diagnostic : Real issue.
Rationale  : When copying flags, first access to
             `use_pfxlist[use_pfxlen]` was garbage if
             `spin->si_compflags` was null.
Resolution : Make sure `use_pfxlist[use_pfxlen]` always has a value (NUL
             if `spin->si_compflags` is NULL).
