I'm not sure why this is so in terms of bash scoping rules, but you can
make etgrep itself a function, like

etgrep() { /bin/grep "$@"; };

at which point you can use it inside of another function (including if
it was defined there).  Instead of unalias, you can remove the function
binding with "unset etgrep".  This should probably work as well for most
purposes.
