Summary: bu_vls_printf doesn't handle complex formats properly
Initial Comment:
This was fixed for a simple case in bug no. 3163487, but this format string doesn't work:
bu_vls_printf(gedp->ged_result_str, "%-*.*s| %-*.*s = %*.*s |\n",
indent, indent, " ",
maxwidth[0], maxwidth[0], fname.rows[i].fields[0].buf,
maxwidth[1], maxwidth[1], table->rows[i].fields[0].buf);
The result works for the first and second '%*.*s' fields but the last field width is ignored (with or without the '-'). I can work around it by building the string with sprintf and feeding that to bu_vls_printf. I'll add a test case later today.

Message:
The actual problem function seems to be "bu_vls_vprintf" in file
"./src/lubbu/vls.c". There is now a regression test for the problem. In
the build directory use "make vls-regress" to run the tests.

Message:
The bug actually exists with a simpler format string as may be seen in the
attached test case. It seems that right justification in a
wider-than-strlen field doesn't work in second or later fields.
