should eliminate hard tabs anyway (so 8 is just in case one gets thru -- LXR was not displaying this source well with 4). - Don't nest jsapi.h outside the idempotent-include #ifndef in dom.h. - Include xp.h to get this code working on Windows (to cope with some kind of compiled header problem). - Fix bad JS_GetEmptyStringValue calls that were treated as returning JSString* rather than jsval, and fed into STRING_TO_JSVAL. - Avoid tagging and untagging a jsval to test for a null JSString* return. - Fiddle formatting in a couple of places. - Avoid leaving cdata->data null after realloc failure. Use of a local temp (data2) also improves generated code by eliminating memory ambiguity.
