By “is supported” I meant “has any special meaning”. In your variant writing `**` is as good as writing `.*.*` in regex: it will work, but it is pointless (and will cause minor performance degradation in many regex engines). > > Note: if you use `~/**/*.ex` in `:args` command it will behave *exactly as OP > requested **even in Vim-3.0***.
