I have set up mercurial to use SemanticMerge for my diff and merge tool as per the instructions here: http://www.semanticmerge.com/documents/SemanticMerge-Mercurial.pdf .
I can merge files ok but if I try and "diff to parent" for a class (from TortoiseHg workbench) a SemanticMerge menu appears displaying merge and diff options. Using Process Explorer shows that no arguments were passed to SemanticMerge when it started.
I have consulted the documentation for extdiff here http://mercurial.selenic.com/wiki/ExtdiffExtension and I cannot see how SemanticMerge should be setup in the mercurial.ini.
I am using TortoiseHg 2.8.2, Mercurial 2.6.3 and SemanticMerge 0.9.34
