[m-rev.] for post-commit review: simplify the creation of .int2 files

[Zoltan Somogyi]

Apart from some code simplification, this completes step 1d.

Since this diff is way simpler than the previous one, and it
also passes bootcheck cleanly, I am committing it. I will deal
with any comments post commit.

Zoltan.
