This only does the foo:123: case, but you should be able to adapt it,
	if [[ $1 =~ ^(.*[^/]):([0-9]+):$ ]]; then
		1=$match[1]
		2=+$match[2]
	fi

I also have a non-regex version commented out, it is arguably less readable,
	if [[ $1 = *[^/]##:(#b)([0-9]##)(#B): ]]; then
		2=+${1[$mbegin[1],$mend[1]]}
		1=${1[1,$mbegin[1]-2]}
	fi

Ahead of this you'll want to check test -f $1 to avoid munging the
argument if the file exists.

Changing the regex to ^(.*[^/]):([0-9]+)[^0-9].*$ should cover two of
your other cases, but you might want to be more restrictive than .*
there, not sure what you want to allow bar to be.
