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

To remove only some changes, without reverting to a prior version, use

merge instead. For example, "merge . --revision -2..-3" will remove the

leaves the pending merge list alone and reverts only the files. Use "bzr

3944
A merge directive provides many things needed for requesting merges:
3946
* A machine-readable description of the merge to perform
3948
* An optional patch that is a preview of the changes requested
3950
* An optional bundle of revision data, so that the changes can be applied
3951
directly from the merge directive, without retrieving data from a
3954
If --no-bundle is specified, then public_branch is needed (and must be
3955
up-to-date), so that the receiver can perform the merge using the
3956
public_branch. The public_branch is always included if known, so that
3957
people can check it later.
3959
The submit branch defaults to the parent, but can be overridden. Both
3960
submit branch and public branch will be remembered if supplied.
3962
If a public_branch is known for the submit_branch, that public submit
3963
branch is used in the merge instructions. This means that a local mirror
3964
can be used as your actual submit branch, once you have set public_branch
3967
Mail is sent using your preferred mail program. This should be transparent
3968
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
3969
If the preferred client can't be found (or used), your editor will be used.
3971
To use a specific mail program, set the mail_client configuration option.
3972
(For Thunderbird 1.5, this works around some bugs.) Supported values for
3973
specific clients are "evolution", "kmail", "mutt", and "thunderbird";
3974
generic options are "default", "editor", "mapi", and "xdg-email".
3976
If mail is being sent, a to address is required. This can be supplied
3977
either on the commandline, or by setting the submit_to configuration
3980
Two formats are currently supported: "4" uses revision bundle format 4 and
3981
merge directive format 2. It is significantly faster and smaller than
3982
older formats. It is compatible with Bazaar 0.19 and later. It is the
3983
default. "0.9" uses revision bundle format 0.9 and merge directive

format 1. It is compatible with Bazaar 0.12 - 0.18.

A merge directive provides many things needed for requesting merges:
4131
* A machine-readable description of the merge to perform
4133
* An optional patch that is a preview of the changes requested
4135
* An optional bundle of revision data, so that the changes can be applied

directly from the merge directive, without retrieving data from a

If --no-bundle is specified, then public_branch is needed (and must be
4140
up-to-date), so that the receiver can perform the merge using the
4141
public_branch. The public_branch is always included if known, so that
4142
people can check it later.
4144
The submit branch defaults to the parent, but can be overridden. Both
4145
submit branch and public branch will be remembered if supplied.
4147
If a public_branch is known for the submit_branch, that public submit
4148
branch is used in the merge instructions. This means that a local mirror
4149
can be used as your actual submit branch, once you have set public_branch

merge directive format 2. It is significantly faster and smaller than

older formats. It is compatible with Bazaar 0.19 and later. It is the
4155
default. "0.9" uses revision bundle format 0.9 and merge directive

format 1. It is compatible with Bazaar 0.12 - 0.18.
