Hisotry expansion allows you to select previous words, but you'll need
to count from the left when retrieving words from the current line: you
can use ":$" to indicate the last argument, which with !# is the
previous argument, but "-" indicates a range, not a negative offset.
There was some discussion about this anomaly a couple of months ago;
it's potentially fixable with some new syntax (I've forgotten if there
was a conclusion).

make foo; ./!#:1

(remember history expansion starts with word 0).  Unfortunately !#:$
gets you the ";" because while history expansion knows about dividing
into words it doesn't know which words are syntactically important.
