Thanks, Mojca!
This may be off-topic but may be fixable easily while you're at it. The source browser on the website does not work properly: it looks like the index is not up to date with the new directory structure after the separation of MkII and MkIV code. For instance, if I search for "sort" in
source.contextgarden.net, the following appears among the top results.
Following the link produces "Internal Error - please restart the application!" perhaps because the file has now moved to tex/context/patterns/mkiv/lang-es.lua in the CONTEXT tree. However just changing the URL does not work and leads to the following error:
Unknown file or directory: tex/context/patterns/mkiv/lang-es.lua
Can you fix this issue? The source browser is very useful but now many search results are not accessible.
