Wikipedia:Talk page guidelines#Editing comments is not a policy but a guideline, so editors are free to use common sense in following its recommendations.
This is what I read in that guideline: "" My understanding is that "" is really far from "it is forbidden to correct typing/spelling errors". Moreover, the meaning of the word "may" in "" is very clear.
I really don't think that my typo fixes have irritated anyone, including their authors,  and .
I can understand that making wikilinks out of names or words even if they are already written could irritate their authors, but I did that on comments from a single editor who would certainly have given me permission to do so.
Please note, however, that I did not completely revert , as I did not restore the wikilinks. I only restored the typo fixes.
Thank you for having provided links to the guidelines and sorry if my edits have irritated you.
