VSCode sometimes opens certain file descriptors whan you run a terminal nested in it.  The tests A04redirect.ztst assumes fd 99 isnot used and hence tries to gather an error message from 

echo >&99

However, if the fd 99 has been previously opened there is no error, the error message is empty andsubsequent comparisons to it fail.

 

In this patch I propose to test fd 99, 100, 101, … until anunused fd is found. With this change the test passes even if the terminal is in VScode.
