@defun current-word &optional strict really-word
This function returns the symbol (or word) at or near point, as a string.
The return value includes no text properties.
The optional argument @var{really-word} is non-@code{nil}, it finds a
word; otherwise, it finds a symbol (which includes word characters and
both symbol constituent characters).
If the optional argument @var{strict} is non-@code{nil}, then point
must be in or next to the symbol or word---if no symbol or word is
there, the function returns @code{nil}. Otherwise, a nearby symbol or
