Without the following, gcc 4.8.0 20121002 complains:
kwsearch.c: In function 'Fexecute':
kwsearch.c:158:3: error: jump skips variable initialization\
[-Werror=jump-misses-init]
goto out;
^

* src/kwsearch.c (Fexecute): Replace a "goto" and "return" with
a simple return statement, eliminating the label, since that was
the sole use.
* src/dfasearch.c (EGexecute): Likewise.
