depending on silent behavior is a dangerous dependancy.

Try this, then scratch your head why:
fconfigure stdout -buffersize 0x400

I'd still like to see the change
reverted.  Who knows how many
scripts depend on silent truncation
of buffersize requests outside
the valid range?

Those buffersizes are invalid.  I'll fix the test suite.

Reassigned to david, this seems to originate in his latest
changes.
