Perhaps.   I cannot parse your sentence starting with "Actually".

Did you read what I wrote above?  I won't repeat it.



Otherwise, if you use emacsclient from within emacs (eg. from the M-x
shell) you will obviously get different results.  Once you hit RET,
emacs changes the position of the cursor, so the current word is not
the same as when you hit RET, and current-word will return nil.

And I don't see how current-word could return t.  At best, it could
return "t", if you had the cursor on a single letter 't'.
