tg 609b311919 more low-hanging fruits for EBCDIC; notes: 
• ord() new, From: Daniel Richard G. <skunk@iSKUNK.ORG>
  ‣ used in some places
• (c - '0') → ksh_numdig(c)	# may take *x++ argument
• (c - 'A') → ksh_numuc(c)	# may NOT take *x+= argument
  ‣ idem for ksh_numlc(c) and 'a'
  ‣ these need changing for EBCDIC
  ‣ add testsuite for this
• use macros more, they exist already often
• use digits_lc[foo] instead of ('0' + foo), especially for letters
• caught another ksh_eq case…
• also caught a maybe-UB overflow check, but we don’t have TIME_T_MAX ☹
