In the trunk build it doesn't hide them. I don't have 1.4.x installed
here to try it.

When you mark as resolved it is assumed that you have sorted out the
conflicts, or that you intend to do so manually. In the trunk build
you get a warning in TortoiseMerge if you try to mark as resolved
while there are still conflicts. At that stage if you say 'yes, mark
as resolved', the temp files are removed and the file left with its
conflict markers.

Now there's an interesting question. If you delete the ancillary
files, TSVN reports the file as modified, but in the commit and check
for modifications dialogs it is still shown in red, which implies
conflicted. SVN still lets you commit, though.
