split: fix commit message numbering error in the test
Before this patch, the test was wrong and the successors of a splitted commits
all had the same commit messages. This patch makes the test right making sure
that the numbering of the split successors is accurate.
""" This extension provides direct access
It is the ability to refer and access hidden sha in commands provided that you
know their value.
For example hg log -r xxx where xxx is a commit has should work whether xxx is
hidden or not as we assume that the user knows what he is doing when referring
to xxx.
