Hi

I also encountered the same issue as I tried to apply MR !5 to my local.

However, the patch successfully replaced the README.txt file with README.md, hence I will move this to needs work to cater the whitespace errors being flagged in the MR !5 patch

Thank you

Hi

I applied the updated MR !5 to my local and confirmed that the patch applied cleanly without the whitespace error, and README.txt was replaced with README.md file, hence the patch is good and functional.

Please look at the screenshot attached for your reference, moving this to RTBC

Thank you
