A few simple experiments reveal interesting things under Linux:

$ test -n "" && for m in ; do echo a ; done
$ if test -n "" ; then for m in ; do echo a ; done ; fi
$ if test -n "" ; then ; for m in ; do echo a ; done ; fi
bash: syntax error near unexpected token `;'
$ if test -n "" ; then                                  
> for m in x ; do echo a ; done ; fi
$ bash -version
GNU bash, version 1.14.7(1)
$ cat sh.sh
if test -n ""  ;\
then\
        for m in ;\
        do echo a ;\
        done;\
fi
$ sh sh.sh

I.e. I can't seem to reproduce the problem.
