shell inserts spurious newline after backquote expansion
I came across a very strange sh bug today.
The attachment is a reduced case (original a configure script). If you
run it, sh will create a file "o". The bug is that sh will insert a
newline where it should not appear.
I tracked it down to commit 0c6fe0fc88 , but I am not convinced that
it actually introduced the bug. If you change MINSIZE to any other
value, the bug at hand does not show anymore. That's why I think that
this commit simply uncovered an existing bug.
Anybody have some clue what is going on?
