The way Emacs saves files is a feature of the DJGPP libc and not of any
particular mode of Emacs itself (AFAIK).  You can use the DJGPP
utilities 'dtou.exe' and 'utod.exe' (provided in djdev201.zip) to
convert DOS text files to Unix and vice versa.

Don't know about this.  Several dos-related bugs were fixed in the
latest Emacs (20.2); you might want to download the original sources and
rebuild.  I'm certain Eli can tell you more.

If you would like to learn more about Emacs-Lisp, you could figure out
how to set a wrapper for the shell function that automatically runs
refresh-display after shelling.  I am not competent enough to write such
code from memory, though.  :-)

When I want to run my programs, I always shell to a command prompt (C-x
C-z or M-x suspend-emacs) and run the program manually.  Emacs under
MS-DOS cannot use true multitasking, and if programs run from Emacs
require some form of console input they are usually screwed.  The best
way to do it is to run from a DOS shell, symify the traceback there, and
if needed, save the traceback to a file and load it in Emacs.  I can
also run gdb (the GNU debugger) through a DOS shell from Emacs.  Once
finished, type "exit" to return to Emacs.

hth!
