Describe your issue

This is a followup to #2372 which supposedly added support for empty lines.

However I still get errors on empty lines / comments or both combined.

numpy

matplotlib

or

numpy
matplotlib

# 

both fail while

numpy
matplotlib
 

where I added a single to show the newline at the end, or

numpy
matplotlib
 #

work.

Note, I run

micromamba install --name test "python=${PYTHON_VERSION}" -f test.txt -v --dry-run

and before that I created an empty env

micromamba create --name test
