    ps: handle incorrect -D values
    
    I just noticed a slight issue with the '-D' option. Basically,
    I accidentally typed something along the lines of:
    
    ps -Dboth-p303
    
    I.E. missing out the "space". Instead of giving an error, it behaved as
    if I'd just typed "ps".
    
    Looking at bin/ps/ps.c, where the -D option is parsed, it doesn't
    error-out if there is no valid match.
    
    This commit fixes the bug.
    
    (cherry picked from commit 3f0b80bc1537c257f3bd68592832ec8cb65e1c58)
