commons-cli chokes on '-' characters

[dmacvicar]

java -classpath /usr/share/java/commons-logging.jar:/usr/share/java/commons-cli.jar:/usr/share/java/lesscss-engine.jar:/usr/share/java/rhino.jar com.asual.lesscss.LessEngineCli spacewalk.less

Exception in thread "main" java.lang.IllegalArgumentException: opt contains illegal character value '-'

It works if all options defined in LessOptions.java that contains '-' are camelcased.

Just ran in to this bug (I'm running 1.5.1 with commons-cli 1.2)
