The option affects how zsh behaves when invoked without -c or -s
and with a first non-option argument that doesn't contain any
slashes. In this situation, shells generally try to find and run
a script with that name in the current directory; if there is no
such script, they try to find one in PATH. PATH_SCRIPT lets you
control whether zsh performs that fallback PATH search. (It does
not affect other PATH searches.)
% cat foo.zsh
cat: foo.zsh: No such file or directory
% cat dir/foo.zsh
print foo
% PATH=./dir
% /bin/zsh -o PATH_SCRIPT foo.zsh
foo
% /bin/zsh +o PATH_SCRIPT foo.zsh
/bin/zsh: can't open input file: foo.zsh
