go importer documentation/exceptions

[jgart]

Hi Guixers,

Here's my experience of learning the right syntax for the go importer:

2022-04-23 16:27:42     <jgart> guix import go 
https://git.sr.ht/~emersion/chathistorysync@0.1.0
2022-04-23 16:27:53     <jgart> guix import go 
https://git.sr.ht/~emersion/chathistorysync@latest
2022-04-23 16:27:58     <jgart> I tried that too
2022-04-23 16:28:00     <jgart> and
2022-04-23 16:28:09     <jgart> guix import go 
https://git.sr.ht/~emersion/chathistorysync@v0.1.0
2022-04-23 16:28:28     <jgart> singpolyma: is this related to the issue you 
have open?
2022-04-23 16:29:41     <singpolyma>    Do you get an error about a tag being 
missing?
2022-04-23 16:31:32     <jgart> here's the exact errors for all three attempts: 
https://paste.sr.ht/~whereiseveryone/dae9350b5680a3960e0e56c6b7c5da5660d3b8a6
2022-04-23 16:32:29     <jgart> looks like a 410: 
https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/410
2022-04-23 16:33:26     <jgart> guix import go 
git.sr.ht/~emersion/chathistorysync@0.1.0
2022-04-23 16:33:30     <jgart> this worked

The Guix docs do not explicitly state that a uri like
https://git.sr.ht/~emersion/chathistorysync@0.1.0 is not allowed:

https://guix.gnu.org/manual/devel/en/html_node/Invoking-guix-import.html

This leaves footguns for new users trying to use the go importer for the
first time since a new user might want to just copy paste the go package's
url into the terminal.

Should we be explicit in the docs about what uri syntax is and is not allowed
or should we provide better exceptions when the go importer blows up?

all best,

jgart
