Latexmk post-processor does not recognise xelatex as latex rule
When compiling using the "XeLaTeX → PDF (Latexmk)" rule, the bottom panel does not list errors/warnings/badboxes, but contains the full latexmk output instead, with a menu per rule.
I'd open a merge request, but that option is not available to me. The single extra line needed can be found in my parse-xelatex-output
branch, which should be ready to merge.
