Update commits in the remote repository doesn't get pulled

[130s]

Reproduction scenario:
Remote is 1 ahead.

On USB running SELFUPDATE.bat yields the following and stops pulling (like this):

19:00:28: *** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'n1s@mac1.win8.(none)')

git pull is too rough for this usage I think, but first I should list possible usecase and choose the best command to update the script.

Re-ran git pull again, then conflict occurred, which can happen with the command (although very bad and we should not let novice users deal with it). So I don't know what to do with this other than labeling invalid for now.

This still occurs for which situation I can't be certain. Unless this is addressed we can't provide tutorial update
