Current code is causing a failure in adding a set containing
a really long list of elements. The failure occurs as soon as
the line is longer than flex read buffer.
When a line is longer than scanner buffer size, the code in YY_INPUT
forces a rewind to the beginning of the string because it does not
find a end of line. The result is that the string is never parsed.
This patch updates the code by rewinding till we found a space.
