I tried to accomodate that by proposing a prefix.  You still showed it
a cold shoulder.  You even cold-shouldered the minimal proposal that
just tried to propose totally uncontroversial things
<http://www.forth200x.org/directories1.html>.

Given that, and more importantly, the fact that many programmers are
not going to use prefixes when they should, leading to problems
downstream, I now think that we should not go for prefixes.
Source-directory-relative should be the default for relative file
names in INCLUDED etc. (and for legacy programs the system can also
try working-directory-relative afterwards, and maybe warn if both
exist).

Ok, I'll try this:

We have a main program with a library in a subdirectory, the library
consisting of several files.  The library wants to refer to its part
with a source-directory-relative file name, and uses the %xxx% prefix
for that:

[~/tmp/vfxtest:87002] cat main.fs
include lib/lib.fs
[~/tmp/vfxtest:87003] cat lib/lib.fs
include %xxx%part.fs
[~/tmp/vfxtest:87004] cat lib/part.fs 
." part" cr
[~/tmp/vfxtest:87005] vfxlin "include main.fs"
VFX Forth for Linux IA32 Version: 4.72 [build 0555]
Including main.fs
Including lib/lib.fs
Including %xxx%part.fs
Err# -258 ERR: Failed to open requested file.
 Source: "lib/lib.fs" on line 1 
 -> include %xxx%part.fs
                       ^

Nope, the %xxx% prefix does not work.
