I suspect that that would break switches to commands. I.e., it would
require quite involved logic to find out that in
dir /a ../blah
/a should not be converted to \a. So that code would have to keep
track which strings have been autocompleted and change / to \ *only*
in those strings.
(I did not quite understand your proposal, i.e., when and which text
would the conversion be applied to, so I apologize if that's what you
suggested.)
PS: The eshell manual is mostly empty, and when I write "help", I get the
output of the cmd.exe's help. Needless to say, eshell does not recognize
commands that are built-in to cmd.exe (copy, for example). I had to guess
myself towards using ls and cp, but how do I then get a list of all *eshell*
builtins?
Furthermore, neither comint with cmd.exe nor eshell like interactive commands.
I have just run "sc" which prints some usage info and a prompt like this:
Would you like to see help for the QUERY and QUERYEX commands? [ y | n ]:
In raw cmd.exe (own window, outside of emacs), when I press 'n', the programm
immediately exits (no need to press enter after n). In eshell, nothing
happens. The shell never returns to the prompt; pressing up/down arrows
cycles through the history, but no input is accepted until I press C-c twice.
Incidentally, the same thing happens in M-x shell, just that after pressing
C-c twice, it becomes visible that all input had been given to the shell,
just that the buffer hadn't been flushed. This is the output after pressing
'n ENTER' to the above prompt:
--

n
C-c C-c
c:\Users\Hue\Desktop>n
'n' is not recognized as an internal or external command,
operable program or batch file.

Pressing 'n' and C-c C-c is OK, i.e., I get the prompt and no extraneous input
has been sent to the shell.

I have also tried to run interactive Lua interpreter through M-x shell and
I had the same issue with interactivity.. basically no input/output to/from
the interpreter has been visible in the shell window.
