QUESTDLG wraps the text automatically at a certain width. Several paragraphs can be obtained by using a cell string, perhaps with an empty string as separator:
Str = ['asdhgaiosdzgoaszdlbas l lashb kjha sd,man bsdljhakshdg v ', ...
'öaiosuh asödh ljhansbd kjash dbkashdg'];
questdlg(Str);
questdlg({Str, '', Str})
Look at the doc textwrap command also.
