Possibly yes, that would be another patch.
The COLUMNS fallback has the annoying effect that changing the terminal width during a long session doesn't affect Mercurial.
I don't follow you here.
> Also, the »Progress extension, windows and carriage return« thread suggests that this problem is a general problem on Windows. It seems to me that it would be much better to subtract/not add 1 to the terminal width on Windows. After all, util.termwidth() is much more useful if it consistently means something like the amount of characters that can safely be written to a single terminal line.
Yes, that's another option.
