Title:
  Gawk interval expression metacharacter is not working as expected

Status in gawk package in Ubuntu:
  Invalid

Bug description:
  The interval expression metacharacter {} is not working as expected.
  The problem specifically being when the interval is defined on the
  first character of the string/record. Otherwise if the interval is
  defined on any other character apart from the first in the string then
  its working as expected.

  INPUT FILE DATA: metacharfile

  jjjas
  jjjjas
  jjjjjas

  COMMAND: 
  # gawk '/j{1,3}as/' ./metacharfile

  EXPECTED RESULT:
  jas
  jjas
  jjjas

  ACTUAL RESULT:
  jas
  jjas
  jjjas
  jjjjas
  jjjjjas
