261
In recursive mode (the default), files are treated the same way

subdirectories that are neither versioned or ignored, and these

2077
Merge will do its best to combine the changes in two branches, but there
2078
are some kinds of problems only a human can fix. When it encounters those,
2079
it will mark a conflict. A conflict means that you need to fix something,
2080
before you should commit.
2082
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2084
If there is no default branch set, the first merge will set it. After
2085
that, you can omit the branch to use the default. To change the
2086
default, use --remember. The value will only be saved if the remote
2087
location can be accessed.
