LYNX-DEV patches for lynx 2.7.1

[John E. Davis]

The following patches affect 3 files.  The most serious bug is the use
of StrAllocCat instead of StrAllocCopy in LYReadCFG.c:

        case 'X':
        if (!strncasecomp(buffer, "XLOADIMAGE_COMMAND:", 19)) {
-           StrAllocCat(XLoadImageCommand, (char *)&buffer[19]);
+           StrAllocCopy(XLoadImageCommand, (char *)&buffer[19]);
        }
        break;

The second patch affects two files and is a cosmetic fix.  Many times,
e.g., while searching and the search fails, lynx will needlessly
redraw the screen.  This behavior has bothered me for some time.  The
following patch will allow the (slang) screen management facility to
make the decision about whether or not to redraw the screen.
