Bug #: 33639
           Summary: wine cmd wrong assignment while using set "var=value"
                    and have spaces after
           Product: Wine
           Version: 1.5.30
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd

Wine cmd wrongly assign space chars into variable name when using `set
"var=value"` form. Spaces after `value"` must not appear in `var`.

This is important thing, because when variable will be inserted into
conditional expression it may failed (I keep ^M char to see spaces). For
example this lines is failed under wine cmd but works under winxp:
----
set "var=value" ^M
if "x%var%"=="xvalue" (echo ok) else (echo fail)^M
----

some test (I keep ^M char to see spaces):

-- start of test.cmd: --

@echo off^M
set var=value ^M
:: space symbol must appear in `var`^M
echo "%var%"^M
^M
set "var=value" ^M
:: space symbol must NOT appear in `var`^M
echo "%var%"^M
^M
-- end of test.cmd: --

start under winxp:

----
> test.cmd

"value "
"value"
----

start under wine cmd:

----
> test.cmd

"value "
"value "
----
