* 30533: Src/utils.c: when processing a change in the value of
COLUMNS, do not assert the change into the tty driver winsize.
The code for this was dead the whole time IPDEF5 was broken and
this seems a bad time to make it live; besides which it is not
consistent about the handling of LINES (which is ignored when
changed by itself, but would be asserted when COLUMNS changes).
* 30530: Src/params.c: fix long-broken IPDEF5 definition to use
the GSU struct, thus fixing problems with values of LINES or
COLUMNS less than 1.
