| I'm not convinced it's worth worrying about.
No, for named pipes I wouldn't be either, that is not a very likely use case.
But Joerg's ". /dev/null" is more likely. . /dev/tty could happen too I guess.
So, it may be that only directories (as file types - maybe block devices too?)
get ignored as candicates for . - and anything unreadable (currently the code
finds the file, and if it ends up being unreadable, you lose - posix actually
requires, as I read it, that we keep looking for a file that is readable -
when searching $PATH of course, the path name case is easy.)
