This fixes a bug in EastMoney, which calls SetFileTypes() with a COMDLG_FILTERSPEC structure in which pszSpec = L"" followed by SetFileName(L"*.fml"). In windows, this matches all *.fml files. In wine, this matched no files. Before this patch, wine did not use filters from the file name field (marked as a FIXME) and a file type entry with an empty spec would match no files (as opposed to leaving the current filter unmodified).
The exact rules worked out by testing in a Windows 10 VM seem to be:
Current filter is initially empty and can be set by typing a filter into the file name field (or SetFileName) or selecting an entry from the file type menu (or SetFileTypeIndex).
Selecting a file type entry with an empty spec leaves the current filter unchanged.
Selecting a file type entry with a non-empty spec clears the file name field if it currently contains a filter.
This was tested using https://github.com/microsoft/Windows-classic-samples/blob/main/Samples/Win7S... (MIT Licensed). There is a c_rgSaveTypes variable at the top which can be modified to various configurations (especially ones that include a COMDLG_FILTERSPEC with an empty pszSpec)
-- v3: comdlg32: add tests for itemdlg file name field filters comdlg32: allow entering a filter in the itemdlg file name field
From: Charlotte Pabst cpabst@codeweavers.com
current filter is initially empty and can be set by typing a filter into the file name field or selecting an entry from the file type menu.
selecting a file type entry with an empty spec leaves the current filter unchanged.
this behavior matches windows more closely and fixes applications that rely on SetFileName() for filtering.

Added tests. The tests revealed that the current_filter file extension adding logic wasn't being done for open dialogs yet, so I fixed that as well.
