[PATCH] Fix for bug-regex11.c

[Jack Howarth]

Ulrich,
   While the new patch fixes bug-regex11.c, it doesn't seem to fix
the make check failure in sed 3.02 when built with..

./configure  --with-regex=

I still see...

cmp ./readin.good tmp.readin
Patience, the dc.sed test is expected to take a while...
../sed/sed -n -f ../dc.sed < ./dc.inp >tmp.dc
cmp ./dc.good tmp.dc
./dc.good tmp.dc differ: char 1, line 1
make[2]: *** [dc] Error 1
make[2]: Leaving directory `/home/howarth/sed-3.02/testsuite'
make[1]: *** [check-recursive] Error 1
make[1]: Leaving directory `/home/howarth/sed-3.02'
make: *** [check] Error 2

Perhaps we need a better testcase.
