patch 9.1.1237: Compile error with C89 compiler in term.c

Problem:  Compile error with C89 compiler in term.c
          (Zoltan Arpadffy)
Solution: split out LOG_TR macro into 2 different macros. LOG_TR1 that
          takes only a single argument and LOG_TRN that takes 2
          arguments. Remove the use of ##__VA_ARGS__ since the macro is
          now always called with 2 arguments (Hirohito Higashi)
