coverage lcov
Expected behavior
I expect it to write to the lcov file without error
Additional context
Add any other context about the problem here.
I was playing with the .coverage -> coverage.lcov conversion and I noticed a different behaviour between coverage 6.5.0 and any 7.x version
version 7 fails with error:
$ coverage lcov
Wrote LCOV report to coverage.lcov

IndexError: list index out of range
while coverage 6 is fine:
$ coverage lcov
Wrote LCOV report to coverage.lcov
But also the report is different,
coverage 6 only reports few files (only from the first --cov)

Probably the fact that coverage 6 is successful is because it is only consider a few files and this other issue was about coverage version 6.3.2, so I don't think it is a regression with coverage 7
