[Bug c++/45145] New: printing tabs fails strangely

[allcock at math dot utexas dot edu]

This should print 100 numbers separated by tabs, then 100 x's separated by
spaces, then 100 x's separated by tabs, then 100 0's (int not char) separated
by tabs. But the last two print fewer than 100--only one line of them.
