            Bug ID: 26922
           Summary: FAIL: gdb.tui/tui-layout-asm.exp: scroll to end of
                    assembler (scroll failed)
           Product: gdb

  Target Milestone: ---

When running test-case gdb.tui/tui-layout-asm.exp with target board
unix/-fPIE/-pie we run into:
...
FAIL: gdb.tui/tui-layout-asm.exp: scroll to end of assembler (scroll failed)
...

Using some printf debugging:

we can see what goes wrong.

We get:
...
wait_for  : '|    0x6b5                               data16 cs nopw
0x0(%rax,%rax,1)       |\

1)=20=20
            |\
'
...
So, AFAIU this is about indentation.

TUI's behaviour doesn't look wrong to me, so I guess it's a question of
updating the test-case.
