Sample test program

Importing file like this works:
-------------------
REGEDIT4

[HKEY_CURRENT_USER\Software\Wine\Direct3D]
"UseGLSL"="enabled"
-------------------

However this command doesn't work:
echo -e
'REGEDIT4\n[HKEY_CURRENT_USER\\Software\\Wine\\Direct3D]\n"UseGLSL"="enabled"\n'
| wine regedit -

This is due to this piece of code:
        if (fread( s, 2, 1, reg_file) == 1)
        {
            if (s[0] == 0xff && s[1] == 0xfe)
            {
                processRegLinesW(reg_file);
            } else
            {
->              rewind(reg_file);
                processRegLinesA(reg_file);
            }
        }

According to MS doing rewind on stdin clears the buffer. Sample program
attached.
