When --[[ style comments are used, the following line gets collapsed into the comment

[TheCycoONE]

Using the default config (though I didn't see any config line that would change it), multiline comments using the --[[ --]] syntax get collapsed into the next instruction.

This is in spite of the empty line that was between the comment and the instruction.

Same Problem

[ZeroKnight]

I found a similar case. Here's a diff showing that the formatter wants to awkwardly join a comment to the end of the previous line:

 -- Formatter Configuration
-
 require('format').setup {
   ['*'] = {
     {
       cmd = {
         -- Trim trailing spaces
-        [[sed -i 's/\s*$//']],
-
-        -- Trim extra trailing newlines (but not the final newline)
-        [[sed -i -e ':a' -e '/^\n*$/{$d; N}' -e '/\n$/ba']]
-      }
-    }
+        [[sed -i 's/\s*$//']], -- Trim extra trailing newlines (but not the final newline)
+        [[sed -i -e ':a' -e '/^\n*$/{$d; N}' -e '/\n$/ba']],
+      },
+    },

Yep, same here

[arkarkark]

here's a nice easy repo case

--[[ hello ]]
local foo = 1
print(foo)

turns into

--[[ hello ]] local foo = 1
print(foo)

I think the local foo = 1 should remain on its own line.
