docs(tutor): add instruction to reload tutor ...

[goyalyashpal]

Problem: Any change to line numbers break the line-number based tests
from *.tutor.json. This is problematic for lessons involving
unbalanced line deletions or insertions.
Solution: Instruct to reload the tutor, thus discarding any edits.
Fortunately, only "Lesson 2.6: OPERATING ON LINES" involves
such line modifications. So, this is needed only there.

Closes: #28164

so, ellipsis are not used in commits with the optional body?
these seemed to help while git log --oneline on CLI etc.

just asking for confirmation before removing these

so, ellipsis are not used in commits with the optional body?

subject is different than body.

your subject ends with "..." , what is the point of that? just remove the "..."

[goyalyashpal]

your subject ends with "..." ,
what is the point of that?

using in git cli,

• where there's no inbuilt hint regarding whether there's any further body to the commit message or not.
• there, it's only these explicit ellipsis in commit title/subject which hint regarding "there's more here", otherwise all look same
• what's more, i think that the ... button on GUIs of github etc is inspired from this convention itself

see below:

i picked this style from some git-commit message guide some time ago.

$ git log --oneline -n4 --no-decorate

Do you plan to finish this? The details about git are off topic.

Do you plan to finish this?

😆 oh lol.

• i had shared all my investigation and conclusion as far back as 2024.04.04 (more than a month ago).
• infact, i was awaiting ur response 😅. u asked me to update, which i did. but nobody never answered even then.

just to iterate here again:

• the only feasible way i could think of to solve this is to reload the tutor,
• and i didn't get any response on how can that be done!

Verbatim quoting:

hi @ justinmk
is it possible to reload/revert the tutor?

• following this: edit-a-file, i tried doing :e! inside the :Tutor, and it showed me blank. ...
• i even tried rerunning :Tutor inside :Tutor, but again showed me blank.

do you have any other thoughts?

This is way too much complication for what appears to be a small problem. Either send a PR that fixes it or it's wontfix.
