If there are other cases where "normally" is used to convey
"by default" then I hope they get fixed too.  If the
surrounding text makes clear, e.g. by explicitly contrasting,
that what is meant by "normally" is the default case, then
it could be OK (but should never be _preferred_ to stating
clearly and explicitly what the default behavior is).

In this case, "normally" might have been able to be understood
the way you say if the last two sentences were in their own
paragraph, so that the last more clearly qualified the
statement of the next-to-last, instead of appearing to stand
on its own.

Correct.  I wouldn't have objected about calling it a word.

But I would have objected about "near", which is not the
same as on-the-same-line-and-adjacent-to - it is quite
different, in fact.

  Return the word at point or adjacent to it, as a string.

(or a bit less clear:

  Return the word at or adjacent to point, as a string.)

See above.

The rest looks good.  Thx.
