The result of 'spdx-string->license' is a symbol, not a license object.
* guix/import/utils.scm (spdx-string->license): Fix docstring.
(license->symbol): Mention 'license:' prefix in docstring.

SPDX specifies that license identifiers (unlike the 'AND', 'OR', and
'WITH' operators) are matched case-insensitively.
* guix/import/utils.scm (%spdx-license-identifiers): New variable.
(spdx-string->license): Search in '%spdx-license-identifiers' using
'string-ci=?'.

Previously, '+' was supported only via special cases for deprecated
GNU identifiers like 'GPL-N+'. This commit adds support
for other uses of '+', such as 'AFL-2.0+' and 'LPPL-1.0+'.
Strictly speaking, '+' is an operator, not part of the SPDX license
identifier, but it is useful to handle it here.
* guix/import/utils.scm (spdx-string->license): Support '+' operator.

Hi,
Applied all three patches. I added trivial tests for
‘spdx-string->license’ and changed ‘substring’ to ‘string-drop-right’,
which I find clearer.

I guess we can remove the “+” forms from the alist now?
Thanks,

I think we still want the "+" forms in the alist so that we continue convert
"GPL-2.0+" as though it were "GPL-2.0-or-later", not "GPL-2.0-only".
Some upstreams probably wrote "GPL-2.0" out of confusion even though they
intended to allow "any later version" (and maybe even said so in prose), which
is why the "+" operator was deprecated for GNU licenses.
If upstream wrote "GPL-2.0+", though, that does communicate "or, at your
option, any later version"; since that's the more compatible case, it seemed
useful to retain that information when we have it.
Ideally, upstream projects should move away from the deprecated identifiers
(the Racket tooling I've written will complain), but they still seem to come
up often enough in the wild to be worth handling as special cases.

Oh right. Then I wonder why the code above (with ‘substring’) doesn’t
replace “+” with “-or-later”?
