In #31, if the pattern (foo) comes more than two times in the line then it replaces the second last one. As an example
echo "this is first foo, this is second foo another foo quux" | sed 's/\(.*\)foo\(.*foo\)/\1bar\2/'
then output will be:
this is first foo, this is second bar another foo quux
Which doesn't fulfill our requirements.
You should do such operations without resorting to greediness of regexes
changes the first "foo" to "bar", no matter how many times "foo" is in the pattern space.
