cql-to-elm translator comment newlines being lost in some cases

[nmorasb]

We are using the cql-to-elm library and have observed that when combining styles of comments the newline after the last comment is lost, causing issues with downstream consumers of the generated ELM.
CQL:

library ObsTestN1 version '0.0.000'

using FHIR version '4.0.1'


include FHIRHelpers version '4.1.000' called FHIRHelpers

parameter "Measurement Period" Interval<DateTime>

context Patient

/* Multi-line works fine */
// Single-line comment does not work
define "boolIpp":
  exists ["Encounter"] E where E.period.start during "Measurement Period"

Here are some screenshots of the issue as observed after passing the ELM to fqm-execution:

The issue is not observed when comment styles are not mixed:

The issue is also not observed if a multi-line comment comes after the single-line comments:

These screenshots were all coming from fqm-execution library output, but we can see here the actual cql-to-elm output where the newline character is being lost:

versus what appears when we only use single-line comment style:

Adding @JSRankins here as well
