Help instructions confusing

[daveplunkett]

The usage instructions for the files parameter show an example glob pattern surrounded by single quotes

 -f, --files string (optional)          Glob pattern that specifies a set of files to upload. For example,
                                         **/*.{pdb,exe,dll} will recursively search for .pdb, .exe, and .dll files.
                                         Defaults to '*.js.map'

However, using single quotes fails for me. I can get it to work with double quotes. Perhaps our usage should show double quotes?
