[PATCH v2 0/2] MR6657: comdlg32: Fix buffer overflow when current_filter is longer than MAX_PATH.

[Charlotte Pabst (＠CharlottePabst)]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=57293

Without this change, the tests segfault due to a buffer overflow.

Note: This bug was surfaced but not caused by b5cbb5562ca1aaf023a588bdc6ccb89220637fc4. Before b5cbb5562ca1aaf023a588bdc6ccb89220637fc4, the savedlg test segfaults while the opendlg test does not. After it, both segfault.
