| OK, will do that (though what that will be is already there...)
Now done. See note 4866. The final text I didn't include as it
would be identical to what is in note 4862.
The one real change is to replace (in a slightly different place)
the words
known only by a filename
with
If the pathname being sought contains no slash ('/') characters,
and hence is a filename,
which is just a more long winded way of saying what the original was
trying to convey. That is, the list of prefixes in PATH is used only
when the pathname is "known only by a filename" - which the reader is
expected to know means "contains no '/' character" as that is what the
definition of "filename" in XBD 2 says it means.
The rest of the change is just a rearrangement of what is there now
to make it appear in (IMO) a more logical order. That is, the most
important thing is that we're taking each prefix in turn, applying
that to the filename, and seeing if it works... The details of how
to merge the prefix and filename in the various cases, is the less
important part, and so comes after we know why we care about those
details.
I also included a (not very good) suggestion of what to do to fix the
"only pathnames starying with a '/' are resolved" (apparent) wording
in the current text.
