wording taken from man page for CURLOPT_URL <https://github.com/curl/curl/blob/04488851e291ea0fc3f32e87ea637afcf1c2ca28/docs/libcurl/opts/CURLOPT_URL.3#L67-L68> As far as I can see, the URL part is either malloc'ed before due to encoding <https://github.com/curl/curl/blob/04488851e291ea0fc3f32e87ea637afcf1c2ca28/lib/urlapi.c#L1512> or it is strdup'ed <https://github.com/curl/curl/blob/04488851e291ea0fc3f32e87ea637afcf1c2ca28/lib/urlapi.c#L1516>.

It would be nice to know how to manage the memory of a newly set URL (part) from the documentation. From reading the respective source file
lib/urlapi.c, I gather that the changes represent that accurately: The string that ends up being written to the URL struct is eithermalloc'ed before either due to encoding or appending a query, or it isstrdup'ed.I made the wording similar to the man page for
CURLOPT_URL:curl/docs/libcurl/opts/CURLOPT_URL.3
