[perl #118817] avoid using 2 handles to write to the debug output
Previously the tests were run with the following config:
NonStop=0 TTY=db.out LineInfo=db.out
This meant that the debugger would write the prologue, command prompts
and their results and the epilogue to one handle, and any line trace
information to the second handle. Since those handles didn't share
file a file position, the line trace info would overwrite the
prologue, and the epilogue would overwrite part of the line trace
info.
When TTY=vt100 on Redhat systems, this made the epilogue just long
enough to overwrite the line trace data that a test matched against,
causing the test to fail.
To fix this, I avoided setting LineInfo:
NonStop=0 TTY=db.out
and since LineInfo defaults to using the TTY handle, both type of
content are written to db.out *without* overwriting each other.
Unfortunately this broke some other tests, since now the command
prompts which were overwritten by line trace information are mixed in
with the line traces - I've modified the tests that failed to account
for the included command lines.
