Now after looking at #3386 where the `in_block_comment()` is used, it's sole purpose is to tell whether to add the initial `*` in multi-line block comment. This now works only for `*` and `+` for D but no other character. Block comments in Julia are introduced by `#=` so we'd have to do the equivalent for the `=` character too and I'm not really sure if Julia users write comments this way: ```Julia #= line1 = line2 = line3 =# ```
or rather just
```Julia #= line1 line2 line3 =# ```
and whether it's something they want.
