strbuf_add_wrapped_text(): factor out strbuf_add_indented_text()
Add a new helper function, strbuf_add_indented_text(), to indent text without a width limit, and call it from strbuf_add_wrapped_text(). It respects both indent (applied to the first line) and indent2 (applied to the rest of the lines); indent2 was ignored by the indent-only path of strbuf_add_wrapped_text() before the patch. Two simple test cases are added, one exercising strbuf_add_wrapped_text() and the other strbuf_add_indented_text().
