desc:
grep could not output matched string in some case

how to reproduce:

   1. put the attached files in a same dir
   2. run the script x.sh
   3. you will see the matched string
   4. run the same command in the script ,it may be looks like this
      - > cat tmp-a.tmp|grep --color=never Location|grep -Eo 'https.*'
   5. you will see a blank line was output. and it should be the same with
   running the script

thanks for any one of you who will fix this bug.
