In shell/command.c the following patch should fix the issue (assuming
switchar changed).

I have uploaded a build to http://www.fdos.org/kernel/command/FreeCom/test/
commandx.com is same as command.com but compressed with UPX
Note this is very minimally tested build.
dif file has a few other minor changes [use switchar for help /? --> -?
and start towards help showing proper switchar]
To change the switchar add
?switchar=-
to config.sys (you can remove the prompt ? if you always want the switchar
changed)
Note: you will need to add a shell line using the proper switchar or you
may get errors about path when /P and /E are parsed as paths instead of
options.
I believe this is based on latest SVN sources, (the diff file is from svn
diff) as compiled with Open Watcom.
