* guix/swh.scm (swh-url): Don't redirect when URL contains 'extid_version'.
(lookup-external-id): Specify 'extid_version' avoiding SWH's bug from past
version.

Hi,

Without the patch:

    $ guix repl
    scheme@(guix-user)> (use-modules (guix swh) (gnu packages guile-xyz))
    scheme@(guix-user)> (lookup-directory-by-nar-hash
                          (content-hash-value (origin-hash (package-source guile-wisp))) 'sha256)
    $1 = "swh:1:dir:218d95849f10fc0691d7dfa80999ce5061e654ef"

This is incorrect.  As explained in:

    https://gitlab.softwareheritage.org/swh/meta/-/issues/5093

The mismatch comes from something unexpected on SWH side.  That had been
corrected and the way to access to the fix is to update the version; hence the
patch.

    $ ./pre-inst-env guix repl
    scheme@(guix-user)> (use-modules (guix swh) (gnu packages guile-xyz))
    scheme@(guix-user)> (lookup-directory-by-nar-hash
                          (content-hash-value (origin-hash (package-source guile-wisp))) 'sha256)
    $1 = "swh:1:dir:1f35a460673e2c8ccf948b8c18cb8c18d2ec24fe"

WDYT?

Cheers,
simon

For the interested reader, here the message from SWH:

    https://sentry.softwareheritage.org/share/issue/840686e1329b484081ac2b07d27cd4aa/

In short, the redirection is not possible here.


Cheers,
simon
