Thank you!
I can confirm that all those anomalies are fixed now.
But new version brings a warning when compiled with gcc:
arrayfuncs.c:659:9: warning: variable 'prev_tok' is uninitialized when used here [-Wuninitialized]
                                 if (prev_tok == ATOK_DELIM || nest_level == 0)
                                     ^~~~~~~~
arrayfuncs.c:628:3: note: variable 'prev_tok' is declared here
                 ArrayToken      prev_tok;
                 ^
1 warning generated.

Also it looks like an updated comment needs fixing/improving:
  /* No array dimensions, so first literal character should be oepn curl-braces */
(should be an opening brace?)

(I haven't look at the code closely.)

Best regards,
