Yes, it will conflict.  IIRC, you need to look back at your patch logs
and figure out how far up the branch you have merged back into mainline,
then merge only the newer changes.

This is correct.  Each changeset in arch includes a "patch-log" (which
is a concept, as well as a physical file in {arch}), which will prevent
you from merging changes twice.  In place of the manual log search then
"svn merge" in svn, we merge branches in arch like this:

$ tla -t star-merge <branchname>

the "-t" is optional and tells arch to put the conflicts (if there are
any) inside the files, so you can more easily see what conflicted.
