I noticed that the term-width setting would always report its default value (80) despite the driver correctly setting the value with SBDebugger::SetTerminalWidth.
(lldb) settings show term-width
term-width (int) = 80
The issue is that the setting was defined as a SInt64 instead of a UInt64 while the getter returned an unsigned value. There's no reason the terminal width should be a signed value. My best guess it that it was using SInt64 because UInt64 didn't support min and max values. I fixed that and correct the type and now lldb reports the correct terminal width:
(lldb) settings show term-width
term-width (unsigned) = 189
