Allow long error messages on a single line

[llamafilm]

Sometimes a long error message is split into 2 lines. This makes it harder to read IMHO, and also hard to parse with a script. Example:

% curl -fD - --retry 5 --retry-all-errors https://google.com/asdfasdf 
HTTP/2 404 
content-type: text/html; charset=UTF-8
referrer-policy: no-referrer
content-length: 1569
date: Tue, 28 May 2024 00:33:21 GMT
alt-svc: h3=":443"; ma=2592000,h3-29=":443"; ma=2592000

curl: (22) The requested URL returned error: 404
Warning: Problem (retrying all errors). Will retry in 1 seconds. 5 retries 
Warning: left.

It looks like it assumes a default terminal width of 79 characters.

curl/src/tool_msgs.c

Line 49 in 53b4dfe

size_t width = (79 - strlen(prefix));

Can this behavior be adjusted? Perhaps use the existing COLUMNS variable or a new one.

Ack, it should check the terminal width. I'll give it a look...

See #13808
