His function deals with the edge case where there is no argument
passed to the source'd file. He wants `source` to behave the same
inside and outside of a function.
For anyone who wants to test this quickly, try the following code:
#!/bin/bash
i() {
printf '%s:' "$FUNCNAME"
local -r f=$1
shift
. "$f" "$@"
}
s() {
printf '%s:' "$FUNCNAME"
. "$@"
}
printf '%s:' "."
. ./s.sh
i ./s.sh
s ./s.sh
where ./s.sh contains:
printf '%s:%s\n' $# "$*"
The output:
% ./test.sh
.:0:
i:0:
s:1:./s.sh
