Set up a base, local, and remote changeset, as well as the working copy state.

Files names are of the form base_remote_local_working-copy. For example,

content1_content2_content1_content2-untracked represents a

file that was modified in the remote changeset, left untouched in the

local changeset, and then modified in the working copy to match the

remote content, then finally forgotten.

  $ hg init repo

  $ cd repo

  $ hg update -q 0

  $ "$PYTHON" $TESTDIR/generate-working-copy-states.py state 3 3

Check which files need to be resolved (should correspond to the output above).

This should be the files for which the base (1st filename segment), the remote

(2nd segment) and the working copy (4th segment) are all different.

Interestingly, one untracked file got merged and added, which corresponds to the

odd 'if force and branchmerge and different' case in manifestmerge().

Check status and file content

Some files get added (e.g. content1_content2_content1_content1-untracked)

It is not intuitive that content1_content2_content1_content4-tracked gets

merged while content1_content2_content1_content4-untracked gets overwritten.

Any *_content2_*-untracked triggers the modified/deleted prompt and then gets

overwritten.

A lot of untracked files become tracked, for example

content1_content2_content2_content2-untracked.

*_missing_missing_missing-tracked is reported as removed ('R'), which

doesn't make sense since the file did not exist in the parent, but on the

other hand, merged-in additions are reported as modifications, which is

almost as strange.

missing_missing_content3_missing-tracked becomes removed ('R'), even though

the remote side did not touch the file
