jdeps follows the GNU-style options which is different than the JDK 
style.  We discussed this issue about consistency and familiarity [1].   
After using jdeps for some time, I admit that I find it hard to switch 
to the new -c short option (and confusing too) but relatively easy to 
move to --classpath option.  Mixing both GNU-style and JDK-style 
inconsistently adopting GNU style is not a good thing while GNU style is 
the direction we are going (e.g. pack200 follows GNU style).
