I have this wiki tree:
+- Multi-Colour Light.md
| +- multicolour-light-crafting-recipe.png
| +- tic-tac-toe-wiring.png
| +- tic-tac-toe-layout.png
I don't seem to be able link to the files inside the images/ or files/ subdirectories. I've worked around the issue for now by creating an orphan branch in the main repository with the files (it depends on #164 to work correctly, though, so it's not working yet), but having to add the wiki files to the main repository defeats the whole purpose of having a dedicated repository for the wiki.
Here's the original version prior to the migration: https://github.com/pgimeno/digiplay/wiki/Multi-Colour%20Light
This looks somewhat similar to upstream bug 4850.
try it yourself at the gogs demo site try.gogs.io - it the same bug is present there then notabug is probably not going to fix it - it should be fixed in gogs
anything non-odious that makes it into the upstream gogs will be merged into notabug eventually
