Fix for external files when using absolute paths on windows.
-- leading "../" sequences and, if found, remove them and mark this
-- path as external.
local link, count = fname:gsub("%.%.%/", "")
- local external = (count > 0)
+ local external = (count > 0) or fname:find(':', 1, true)
-- Try to provide a little bit of flexibility by allowing virtual
-- paths for external files. Would be great to support them for all
