Hi,

It appears there might be problem with this patch. Here is a test case I
distilled from the grep-2.5.1a testsuite:

status=`echo '-'| { ${GREP} -E -e 'a\' >/dev/null 2>&1 ; echo $?; }`

Put that line into a file called "myfile" then run like this:

# bash -n myfile               
myfile: line 1: unexpected EOF while looking for matching `''
myfile: line 2: syntax error: unexpected end of file

AFAICT, this used to be accepted by older Bash versions.

Do think problem lies with this Bash patch or with test case?

Thanks
Greg
