             Summary: Wrong cursor position after deleting all characters in second line
                 Key: WFCORE-1755
                 URL: https://issues.jboss.org/browse/WFCORE-1755
             Project: WildFly Core
          Issue Type: Bug
          Components: CLI
    Affects Versions: 3.0.0.Alpha3
         Environment: Fedora 24
Gnome Terminal 3.20
Bash 4.3.42
            Reporter: Tomas Hofman
            Assignee: Tomas Hofman


In CLI, when typing expression that stretches more then one line, and then deleting all characters in the last line (using backspace), cursor appears on wrong position on the previous line (should be on last column, but is on column before the last).

Further editing messes up the displayed expression, which doesn't reflect the real content of the buffer.

*Reproducing:*

* Terminal width is 80 characters.
* [] marks a cursor position.

Step 1. - I have expression spreading over two lines like this:

{code}
[standalone at embedded /] /subsystem=datasources/data-source=ExampleDS/connection-
factory[]
{code}

Step 2. - Delete "factory" word using backspace:

{code}
[standalone at embedded /] /subsystem=datasources/data-source=ExampleDS/connection-
[]
{code}

Step 3. - Another backspace:

{code}
[standalone at embedded /] /subsystem=datasources/data-source=ExampleDS/connectio[n]
{code}

while expected is:

{code}
[standalone at embedded /] /subsystem=datasources/data-source=ExampleDS/connection[]
{code}

Step 4. - Another backspace:

{code}
[standalone at embedded /] /subsystem=datasources/data-source=ExampleDS/connecti[]n
{code}

while expected is:

{code}
[standalone at embedded /] /subsystem=datasources/data-source=ExampleDS/connectio[]
{code}
