It seems that when a Gemini URL without a trailing slash but 
corresponding to a directory is requested it's not redirected to the 
same URL with a trailing slash. For example 
gemini://sotiris.papatheodorou.xyz/gemlog isn't redirected to 
gemini://sotiris.papatheodorou.xyz/gemlog/ as expected.

This behavior breaks relative links in the response since they're rooted 
on gemini://sotiris.papatheodorou.xyz/ instead of on 
gemini://sotiris.papatheodorou.xyz/gemlog/.

I've got a patch that might fix this issue (pasted below) but no easy 
way to test it. I have managed to package the patched version (by 
modifying a manifest from some build on lists.sr.ht) but I'm not sure 
how to test that the issue is fixed.

Any help is welcome.
