--- Comment #1 from Bernhard Übelacker <bernhardu at mailbox.org> ---
Came across this report because the launcher for "syngo fastView" triggers this
problem too.

It looks like the quotes get removed in kernel32/process.c, function
build_argv.

This does not yet work if it contains a space. But adding another pair
unescaped
quotation marks around would work again:
c:\>start "\"a b\"" wineconsole

Therefore, just for completeness, there is probably a third way:
In cmd/builtins.c WCMD_start encode simple quotes to escaped quotes with
surrounding quotes.

But I don't know which way would be the best.
