Glob with brace expression not working

[bogdang989]

Expected Behavior

glob: {*.txt,*.png} should match all of the braced patterns.

Actual Behavior

Nothing is returned.

Workflow Code

class: CommandLineTool
cwlVersion: v1.0
baseCommand:
  - ls
inputs:
  - id: input
    type: string?
outputs:
  - id: output
    type: File[]
    outputBinding:
      glob: '{*.png,*.txt}'
requirements:
  - class: DockerRequirement
    dockerPull: 'ubuntu:16.04'
  - class: InitialWorkDirRequirement
    listing:
      - entryname: a.txt
        entry: a
      - entryname: b.png
        entry: b
stdout: b.txt

Brace expression isn't part of the POSIX glob syntax, that is a BASH-ism.

For this example, here's a working version:

class: CommandLineTool
cwlVersion: v1.0
baseCommand:
  - ls
inputs:
  - id: input
    type: string?
outputs:
  - id: output
    type: File[]
    outputBinding:
      glob: 
        - *.png
        - *.txt
requirements:
  - class: DockerRequirement
    dockerPull: 'ubuntu:16.04'
  - class: InitialWorkDirRequirement
    listing:
      - entryname: a.txt
        entry: a
      - entryname: b.png
        entry: b
stdout: c.txt

Or with an inline YAML list: glob: [ *.png, *. txt ]

Tnx @mr-c for the clarification. I guess I should close the linked PR as well then?
