bug#44351: Bug in grep v3.2 onwards in regular expression matching

[Norihiro Tanaka]

Example,

  a+a+a
  1 2 3

position 1 has a repetition of "a" and other transition with "a".
position 2 has a repetition of "a" and other transition with "a", too.
Then DFA was merging the two nodes, but it is wrong.

Now similar nodes in series are not merged.
