Fix record.cwl to make section 11 workable for record-job2.yml

[tom-tan]

Currently an example record.cwl with record-job2.yml in section 11 does not return the same result as shown in the section.

Expected:
Section 11 shows that (itemC is chosen):

$ cwl-runner record.cwl record-job2.yml
[job 140566927111376] /home/example$ echo -A one -B two -C three
-A one -B two -C three
Final process status is success
{}

Actual (itemD is chosen):

$ cwl-runner record.cwl record-job2.yml
/Users/tom-tan/.pyenv/versions/3.6.2/bin/cwl-runner 1.0.20170908110401
Resolved 'record.cwl' to 'file:///Users/tom-tan/repos/user_guide/_includes/cwl/record.cwl'
[job record.cwl] /private/var/folders/gk/zyzswjbs6m59ywz69zhrtmlh0000gn/T/tmpgyqxniuj$ echo \
    -A \
    one \
    -B \
    two \
    -D \
    four
-A one -B two -D four
[job record.cwl] completed success
{}
Final process status is success

After merging this request:

$ cwl-runner record.cwl record-job2.yml
/Users/tom-tan/.pyenv/versions/3.6.2/bin/cwl-runner 1.0.20170908110401
Resolved 'record.cwl' to 'file:///Users/tom-tan/repos/user_guide/_includes/cwl/record.cwl'
record-job2.yml:6:3: invalid field `itemD`, expected one of: 'itemC'
[job record.cwl] /private/var/folders/gk/zyzswjbs6m59ywz69zhrtmlh0000gn/T/tmpef_u3_sk$ echo \
    -A \
    one \
    -B \
    two \
    -C \
    three
-A one -B two -C three
[job record.cwl] completed success
{}
Final process status is success

It shows the same command shown in the section. Also, latest cwl-runner prints a good warning for exclusive parameters.

Good catch, thank you @tom-tan. Sorry that it's taken me a month to get to this. I wonder if the formatting problem here is also affecting other .cwl files in the examples... 😟
