Odd Conflicts (EOL issues) in repo converted from VSS

From: Damian Sinclair <Damian.Sinclair_at_homechoice.net>

 We recently moved to Subversion from VSS, using a script (VSS2SVN, I
believe). This created a repository in which we have a number of
branches that have no SVN history of being copies of the trunk. The hit
of having to coddle the merging of these branches back into trunk as
they go for release is understandable, but we're seeing issues with
conflicts that don't make complete sense, and I'm hoping someone can
confirm my suspicions or set me straight as to what the problem is and
how to fix it.

 The situation we're seeing is that we are merging the unlinked (no
historical copy from trunk) branch back to trunk and we see conflicts
where the files are actually identical or contain trivial changes(as in
no changes occurred in the merge-to target) in a tool such as
TortoiseSVN. When we look at these "conflicted" files, what we see is
that they whenever they have been edited and commited post-VSS
conversion, every line is shown as having been deleted and then
re-added, with the difference being that the VSS version has CRLF eol
markers and the next version has LF eol markers.

 We've set all our clients (we work on both Windows and Linux) to native
eol, but what appears to have happened is that the original import
somehow preserved the Windows eol markers from the VSS repo. Now, when
we make a change, SVN converts the entire file to Unix eols and then its
internal diff defines that commit as conflicting in all circumstances.

 My concern is that merging will continue to produce a long list of
unresolved conflicts when it shouldn't actually need any manual effort.
How should I fix this? Is there any way to get SVN to convert all the
files internally, or preferably to ignore eol issues when doing diffs?

 Thanks for any help,

Damian Sinclair
