the reason for adding newlines after ;'s is that there have been problems 
with the metapost buffer length

i didn't test itm, but maybe

             s/(btex.*?)\;(.*?etex)/$1\@\@\@$2/gmois;
             s/(\".*?)\;(.*?\")/$1\@\@\@$2/gmois;             # add this line
             s/\;/\;\n/gmois;
             s/\n\n/\n/gmois;
             s/(btex.*?)\@\@\@(.*?etex)/$1\;$2/gmois;
             s/(\".*?)\@\@\@(.*?\")/$1\;$2/gmois;             # and this one

somewhere around line 2260 in texexec.pl will help
