The problem is that, apart of Bash, the rest of DJGPP (and non-DJGPP
programs) don't understand this syntax, so Bash has to translate this
back to the DOS d:/dir form.  But for this, Bash should know which
arguments are filenames and which aren't, which is hard.  So Bash does
the conversion in all such cases.  A frequent case where this logic
fails is with Sed scripts which usually include slashes.

Another problem is that this conversion couldn't be done for Bash
internal commands such as `echo', because it would again break some
Unix scripts which use `echo' to transform variable names (as in
"echo $foo | sed -e ...").  Enabling the conversion for external
commands only is better, but it doesn't always work either, e.g., when
the echoe'ed string is used as part of command line passed to a
program.

In short, it's a mess.
