[RESEND] regedit: Convert from WCHAR size to maximum required TCHAR size.

[Byeong-Sik Jeon]

Hi,

MS-Windows's RegQueryKeyInfo function test result:

1. MSDN means TCHARS when it says 'character' for this function.
    ==> No.
2. why RegQueryInfoKey is returning a number that is too small
    ==> No. Currently Wine's RegQueryInfoKey set the right values.

Thank you.
