I'm sure they would, but hard links are cheaper, and they don't require...

...any such support from the operating system, (nor from any add-on). 
OTOH, hard links can only be used with physical disk files, and they 
cannot span devices, (neither of which represents a problem in the 
scenario under discussion).

You can infer the name of the command from the link name itself; 
something along the lines of:

   #!/bin/sh
   CMD=`basename "$0"`
   $CMD.exe "$@"

or, if you need to insert a command specific path:

   #!/bin/sh
   CMD=`basename "$0"`
   case $CMD in
     bzr) /path/to/$CMD.exe "$@" ;;
     ...
   esac

should do the trick, for either hard links or for symlinks.
