  New Revision: 65630

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=65630

  Log:
    avoid (size_t)-- (2nd try)
    
    The decrements overflow and these variables remain ~0 when leaving the
    while loops.  They are not fatal by accident, but better replace with
    ordinal for loops.
