Comment(by Denis-de-Bernardy):

 k... 9930.2.diff does the following:

  - it extends the second regex so that it catches doubles like 1E+1.
  - it reduces backtracking for the second regex

 more specifically for the second:

  - an anchored regexp is very fast, unless it needs to match the entire
 string (as it currently does)
  - substr() is very fast, and it's trivial to see if a string has one out
 of two values

 so by splitting the test in two, we get the same semantics and we make it
 faster and less resource hungry.
