Unable to load files via CLI -input if filename has spaces on Windows

[earlhood]

The use of -input:[filename] does not work if filename contains spaces under Windows Command Prompt. Attempts to surround entire argument in quotes, or just the filename component, does not work.

Examples that fail to work:

HDRImageViewer.exe -input:"file with spaces.jxr"

HDRImageViewer.exe "-input:file with spaces.jxr"
