with the change to status -f output a realpath implementation would be useful #2932
Description
If you are symlinking scripts that rely on status -f being resolved to the original source, you will get the wrong file. Is this the correct behaviour of status -f and if so, is there a way to get the real path of the currently executed script?
Reproduction Steps:
mkdir -p /tmp/dir1mkdir -p /tmp/dir2echo 'status -f' > /tmp/dir1/real.fishln -s /tmp/dir1/real.fish /tmp/dir2/link.fish
Expected behavior:
$ fish /tmp/dir1/real.fish
/tmp/dir1/real.fish
$ fish /tmp/dir2/link.fish
/tmp/dir1/real.fish
Observed behavior:
$ fish /tmp/dir1/real.fish
/tmp/dir1/real.fish
$ fish /tmp/dir2/link.fish
/tmp/dir2/link.fish
