yes - now that I looked more carefully.  I added a to-do item to fix it.

A recent/earlier discussion here

        http://lists.gnu.org/archive/html/bug-ncurses/2019-02/msg00019.html

dwelt upon the differences between the "tabs" command-line utility
versus the library, and this appeared to be a followup.  (At the
time, I added notes on how I might make that gap easier to bridge
with a few new functions).

actually the fputs has to be altered as well, e.g., first check that init_tabs
is nonzero, and then eliminate the fixed-length string:

        printf("%*s", init_tabs, " ");
