How does Mercurial handle splitted files?

filesplitting, mercurial, merge

Solution

After reading the clarification comment, the answer is no. Mercurial tracks files, not hunks of code, so it can't do that as far as I know.

Problem

How does mercurial handle splitted files? What will happen if I create a branch and split a file. Can I easily pull changes from another branch which modifies the original, unsplitted file?
