Hello, Ed!
Spaces in file names make LOTS of troubles for current shell support in XEmacs.
May be you would be pleased to know that GNU Emacs is in trouble too :))
XEmacs tries to simulate changes of directory in shell by parsing shell
commands and trying to predict the new directory and directory stack. The
working engine is `shell-directory-tracker' that uses `comint-arguments' to
parse.
The patch below is a quick-wrong patch that solves the problem with TAB
completion for `cd' command. Still lots of problems with spaces in
file names remain.
Another problem is with quotes around directory name. For example,
c:
cd \
cd "Program Files"
XEmacs does not understand that after the last command the working directory is
c:\Program Files\. Reason is that `comint-arguments' does not strip quotes
from extracted arguments.
Nick.

EA> ================================================================ Dear Bug
EA> Team!
EA> I installed a prebuilt binary of XEmacs for Windows using the Net
EA> Installer (linked from the xemacs.org site) and installed all packages.
EA> I can start M-x shell to create a shell buffer running the Windows
EA> command prompt cmd.exe. In that buffer pressing Tab normally completes a
EA> filename. But this does not work when the directory name before Tab
EA> contains spaces.
EA> To reproduce:
EA> - Install XEmacs in c:\program files\xemacs
EA> - Start XEmacs
EA> - M-x shell
EA> - c : RET
EA> - c d \ RET
EA> - (Prompt now says 'C:\>'.)
EA> - c d SPC p r o TAB
EA> - (Filename completes to 'program Files\'.)
EA> - RET
EA> - (Prompt now says 'C:\Program Files>'.)
EA> - c d SPC x e m TAB
EA> - (Status line says 'No completions of xem'.)
EA> Expected behaviour: 'xem' would be completed to 'xemacs\' since
the
EA> directory c:\program files\xemacs exists.
EA> Tab completion seems to work as normal inside directories which do not
EA> have spaces in their names.
EA> A similar completion problem happens outside shell buffers, when trying
EA> to visit a file with C-x C-f. I can tab-complete successfully only
EA> inside directories which do not have spaces in the name.
