----------------------------------------------------------

I was wondering why this issue didn't make it into 1.4. I'm affected by this issue in combination with combined options (like described in #216). Example:

{code}
Usage: foo [-c | -e | -h | -l | -s | -v] [-d]
 -c,--check     Check configuration settings.
 -d,--debug     Turn on debug messages.
 -e,--extract   Extract data from rdbms into csv files.
 -h,--help      Show this usage text.
 -l,--load      Load csv files into neo4j.
 -s,--setup     Configure settings interactively.
 -v,--version   Show the version.
{code}

Specifying "-dc" passes debug and check to the application. However, specifying "-de" does not pass debug and extract to the application but is instead interpreted as a "long option", even though a single minus sign is used.
