Details:

I believe there is a small bug in kawa/lib/files.scm which results in the ~d
in a template such as "kawa~d.tmp" not being replaced by a suitable string
(which I assume is the intention).

>From what I can tell based on a quick look, changing #\~ to "~" in an indexOf
invocation (in the make-temporary-file procedure) fixes things (context diff
also attached):

$ diff  kawa/lib/files.scm~ kawa/lib/files.scm
164c164
<          (tilde (fmt:indexOf #\~))
---
>          (tilde (fmt:indexOf "~"))
 
I guess adding an explicit type specifier may be a better fix, but the above
seems to do the trick.

All the above is using a SVN version of Kawa from earlier today:

$ kawa --version
Kawa 2.1.9 (revision 8992M)
