qemu-options: Improve -global documentation
Recent commit 3751d7c
"vl: allow full-blown QemuOpts syntax for
-global" overloaded its existing argument syntax DRIVER.PROP=VALUE
with QemuOpts syntax. Unambigious as long as no DRIVER contains '='.
Its documentation claims that "the two syntaxes are equivalent."
Improve it to spell out how exactly the old syntax gets desugared into
the new one.
