Before I answer Reinhard's message, I'd like to mention I committed
something that should work around the problem. It should be in the
updates of tomorrow if your CTAN mirror is very up-to-date, or a bit
later otherwise. You can still try it by manually installing the two
attached files in bin/win32 (texdoc.bat overwrites the current, the
other file is new).

I'm sorry, but if I remember correctly, I tested this too and it fails
too. Testing it again: well, just nothing visible happens. No error, no
program starting, nothing. Since I don't know how to test exits codes on
windows, I can't say if the os.spawn failed or something else.

By the way Philip, if you know of a good "Windows for the command line
addict" tutorial... (and details such as how to set environment
variables, etc.)

Btw, I'm now doing my test on a virtual machine. On of the advantages is
that you can take snapshots very easily and have no fear breaking
everything :-)

Btw you can also put viewer_pdf=print_argv in your texdoc.cnf and make
sure print_argv is in your path, if you want to avoid overwriting
acrord32 or start (which may be a shell builtin btw). Here is the result:

C:\Program Files\texlive\texmf-local\texdoc>echo viewer_pdf=print-argv >

C:\Program Files\texlive\texmf-local\texdoc>texdoc texlive-en
argv[0]: __print-argv__
argv[1]: __C:\Program

(The other very nice thing with virtualbox is copy-pasting between guest
and host machines.)
