[patch][win32] Fix multibyte fontname

[Ken Takata]

Hi,

On Win32, "_" can be used instead of a white space for 'guifont' for convenience.
For example, when a user sets "guifont=MS_Gothic", vim will also search a font
named "MS Gothic".
However, I found that this doesn't work well when a font name contains a
character which includes "_" as a part of it. E.g. The second byte of "柔" is
the same as "_" in the cp932 encoding. So ":set gfn=源柔ゴシック等幅_Regular"
doesn't work as expected. (":set gfn=源柔ゴシック等幅\ Regular" works.)

Attached patch fixes the problem.
