Done.

This was already fixed in Emacs 25.1.

I don't understand what are you saying here.  Sure, it's some text at
point, but the form of that text might describe a symbol, an
expression, a string, etc.

I changed that to say "the entity at point" because the rest of the
doc string refers to that.

Added.

> 5. Typo: "function of no argument" should be "function of no arguments".

Fixed.

> 6. " where" should be ", where:" (and that sentence is run-on (too

Done.

> 7. "responsible to preserve" should be "responsible for preserving".

Done.

Thanks.
