+ * [w3m-dev 02700] search refactoring
+ * based on http://www.nmn.jp/~hidai/software/w3m/
+ * fm.h: add SR_* constants, result value for search
+ * main.c (srchcore): added
+ * main.c (disp_srchresult): added
+ * main.c (srch): added
+ * main.c (srchfor): use srch()
+ * main.c (srchbak): use srch()
+ * main.c (srch_nxtprv): use srchcore() & disp_srch_result()
+ * search.c (forwardSearch): return SR_* result value
+ * search.c (backwardSearch): ditto

* [w3m-dev 02699] initialization too late
* main.c (MAIN): initializations moved before arg processing
* debian bug closes: Bug##102445: ignores SIGWINCH while downloading
