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

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

changes introduced by -2, without affecting the changes introduced by -1.

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

4013
A merge directive provides many things needed for requesting merges:
4015
* A machine-readable description of the merge to perform
4017
* An optional patch that is a preview of the changes requested
4019
* An optional bundle of revision data, so that the changes can be applied
4020
directly from the merge directive, without retrieving data from a
4023
If --no-bundle is specified, then public_branch is needed (and must be
4024
up-to-date), so that the receiver can perform the merge using the
4025
public_branch. The public_branch is always included if known, so that
4026
people can check it later.
4028
The submit branch defaults to the parent, but can be overridden. Both
4029
submit branch and public branch will be remembered if supplied.
4031
If a public_branch is known for the submit_branch, that public submit
4032
branch is used in the merge instructions. This means that a local mirror
4033
can be used as your actual submit branch, once you have set public_branch
4036
Mail is sent using your preferred mail program. This should be transparent
4037
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4038
If the preferred client can't be found (or used), your editor will be used.
4040
To use a specific mail program, set the mail_client configuration option.
4041
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4042
specific clients are "evolution", "kmail", "mutt", and "thunderbird";
4043
generic options are "default", "editor", "mapi", and "xdg-email".
4045
If mail is being sent, a to address is required. This can be supplied
4046
either on the commandline, or by setting the submit_to configuration
4049
Two formats are currently supported: "4" uses revision bundle format 4 and
4050
merge directive format 2. It is significantly faster and smaller than
4051
older formats. It is compatible with Bazaar 0.19 and later. It is the
4052
default. "0.9" uses revision bundle format 0.9 and merge directive
4053
format 1. It is compatible with Bazaar 0.12 - 0.18.

A merge directive provides many things needed for requesting merges:
4200
* A machine-readable description of the merge to perform
4202
* An optional patch that is a preview of the changes requested
4204
* An optional bundle of revision data, so that the changes can be applied
4205
directly from the merge directive, without retrieving data from a

If --no-bundle is specified, then public_branch is needed (and must be
4209
up-to-date), so that the receiver can perform the merge using the
4210
public_branch. The public_branch is always included if known, so that
4211
people can check it later.
4213
The submit branch defaults to the parent, but can be overridden. Both
4214
submit branch and public branch will be remembered if supplied.
4216
If a public_branch is known for the submit_branch, that public submit
4217
branch is used in the merge instructions. This means that a local mirror
4218
can be used as your actual submit branch, once you have set public_branch

Two formats are currently supported: "4" uses revision bundle format 4 and
4222
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
4224
default. "0.9" uses revision bundle format 0.9 and merge directive

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