Possible bug?

[Pavel Tavoda]

When I define parameter like:

@Parameter(names = {"-o", "--outputFile", "--output-file"}, description = "Output file, if not specified calculated automatically")
String outputFile;

And in builder I allow abbreviations (allowAbbreviatedOptions(true)) and using on command line parameters like:

--OUt output.file

I have got following error:

Error parsing arguments: Ambiguous option: --OUt matches [--outputFile, --output-file]

I understand what does it mean, however I think when it's used on same parameter it's clear which parameter I would like to set (is not ambiguous).
