[NTG-context] puzzling metafun graphics

OK, I'm answering my own post. The plot thickens. It looks like this  
has something to do with file names. It only happens when I have a  
name with a period in it. Thusly, file 05.11.08.tex will not run MP  
to PDF, when I copy the exact same file to 05_11_08.tex, everything  
works as it should.

This may have something to do with the fact (as I just found out)  
that newtexexec doesn't even want to touch these files. I have two  
identical files in a directory, one called 05.10.18.tex, the other  
05_10_18.tex. Here's what happens when I run newtexexec on them:

TeXExec | processing document '05.10.18.tex'
TeXExec | runtime: 0.006379

(and that's it. No output, no action)

TeXExec | processing document '05_10_18.tex'
TeXExec | tex processing method: context
TeXExec | TeX run 1
TeXExec | tex engine: pdfetex
TeXExec | tex format: cont-en
TeXExec | progname: context
This is pdfeTeX, Version 3.141592-1.30.3-2.2 (Web2C 7.5.5)
\write18 enabled.
entering extended mode

ConTeXt  ver: 2005.09.08  fmt: 2005.9.9  int: english  mes: english


and so on.

Bug or feature? You decide, Hans!
