set width: how to restore to auto

set width: how to restore to auto

To avoid line wrapping in backtrace we use:

    set width 0

How to restore it to auto without resizing the terminal?
Why after resizing the terminal defined width is lost?

Looks like there is not enough control over this parameter to implement two
backtrace macros with and without line wrapping.

I guess having "set width/height auto" would make sense.

Indeed, "auto" could fix this, by making anything non-auto stick.

I suggest filing a bug report about this.

If it's just the one command you want to wrap, you can do:

 (gdb) alias bt0 = with width 0 -- backtrace
 (gdb) bt0 [ARG...]
