Re: relative includes in r7rs library definitions

[Seth Alves <alves at hungry dot com>]

Here's a contrived example of the situation I'd like kawa to handle.  
The directory structure looks like this:

./test-kawa.scm
./foo.sld
./foo.scm
./blerg/foo.sld
./blerg/foo.scm

The two foo.scm files define functions of the same name but with 
different return values.  The two foo.sld files wrap their respective 
foo.scm files into r7rs libraries.  test-kawa.sld imports both and 
avoids a name conflict with (prefix ...).

Without -Dkawa.include.path='|:.' it prints:

this is the second one
this is the second one

(unless I cd to another directory before running the script... *then* I 
get the desired output.  This helps illustrate why search paths should 
be relative to the including file, not the user's current directory)

with it, I get a crash.

./test-kawa.scm:12:32: unexpected exception while compiling: 
java.lang.IllegalArgumentException: Illegal character in path at index 
37: ./scheme/base.sld-Dkawa.include.path=|
java.lang.IllegalArgumentException: Illegal character in path at index 
37: ./scheme/base.sld-Dkawa.include.path=|
    at java.net.URI.create(URI.java:859)

The output I'm hoping for is

this is the first one
this is the second one

Please see attached.
