Format comments as haddock

[bsima]

I was browsing the comments and wanted to read them as docs in haddock.

Thank you for this! It looks like haddock for ghc < 8.6 do not like the documentation of individual arguments, e.g. -- | minEntryId. Could you push a patch that removes these two lines?

Pretty sure for arguments you use -- ^ after the argument.

ilterLogFiles :: Maybe EntryId  -- ^ minEntryId
              -> Maybe EntryId  -- ^ maxEntryId
              -> [(EntryId, FilePath)] -> [(EntryId, FilePath)]

@ddssff Done!
