- Note that this detects a "break" in the inner loop, and exits

-
- - The outer loop learns about the inner loop's end condition, and
- stops iterating if it detects the inner loop didn't reach its
- end. In other words, the outer loop keeps going only if the
- inner loop reached its end cleanly [(osect) ==
- (objfile)->sections_end].
-
- - OSECT is initialized in the outer loop initialization
- expressions, such as if the inner loop has reached its end, so
- the check mentioned above succeeds the first time.
-
- - The trick to not clearing OBJFILE on a "break;" is, in the outer
- loop's loop expression, advance OBJFILE, but iff the inner loop
- reached its end. If not, there was a "break;", so leave OBJFILE
- as is; the outer loop's conditional will break immediately as
- well (as OSECT will be different from OBJFILE->sections_end). */
