I have a pre-commit hook to detect mergeinfo
below root, and remove it whenever it occurs
For clarity: the pre-commit hook detects and rejects. The one removing
the mergeinfo is me, using svn propdel.
Someone asked for the hook code, here it is. It's not my submission for
a beauty contest and there are some unrelated checks in there. I use the
SVN command line instead of python bindings because I can't find the
slightest explanation on them.
