1- clone the repo on github 2- clone the clone locally 3- patch the file 4- commit (with a meaningful commit message) 5- push the patch to the clone on github 6- go to the github web to post a pull request.
Plus, that would leave a trace on my github account (I assume that I could:
7- delete my github clone.
but only after the pull request is acted upon (which even if automatic is bound to take some time during which this github activity could be seen).
The lesson here is that providing small patches is too costly.
