Subject: curl: show ipfs and ipns as supported "protocols"
X-Git-Tag: curl-8_6_0~217
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=102de7aa8d5bfc6ed5fe85e89c7b943d0c186f03;p=thirdparty%2Fcurl.git

curl: show ipfs and ipns as supported "protocols"

They are accepted schemes in URLs passed to curl (the tool, not the
library).

Also makes curl-config show the same list.
