r.removeLeadingComments fails when two lines of preceding comments are interrupted by a blank line

[jbullock35]

Describe the bug r.removeLeadingComments usually removes comments on preceding lines when those lines are submitted to the terminal. But if a line of R code is preceded by three lines that have a specific configuration—a comment, followed by a blank line, followed by another comment—the second comment will be submitted to the terminal even if r.removeLeadingComments is TRUE.

To Reproduce

1. In settings, enable r.removeLeadingComments
2. Send this code to the terminal:

# comment 1

# comment 2
print("When you submit this line to the terminal, the second comment will be submitted, too.")

You will see that "#comment 2" has been submitted to the terminal, even though it shouldn't be.

Can you fix this issue by yourself? (We appreciate the help) No, I'm afraid not.

Expected behavior In the example above, the print line should be submitted to the terminal, but no comment should be submitted.

Environment (please complete the following information):

• OS: Windows 10
• VSCode Version: 1.82.0
• R Version: 4.3.1
• vscode-R version: 2.8.1
