last committed revision is used.
3124
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.

When you provide files, you can use their current pathname or the pathname

list as well as reverting the files. If any files are specified, revert

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

3997
A merge directive provides many things needed for requesting merges:
3999
* A machine-readable description of the merge to perform
4001
* An optional patch that is a preview of the changes requested
4003
* An optional bundle of revision data, so that the changes can be applied
4004
directly from the merge directive, without retrieving data from a
4007
If --no-bundle is specified, then public_branch is needed (and must be
4008
up-to-date), so that the receiver can perform the merge using the
4009
public_branch. The public_branch is always included if known, so that
4010
people can check it later.
4012
The submit branch defaults to the parent, but can be overridden. Both
4013
submit branch and public branch will be remembered if supplied.
4015
If a public_branch is known for the submit_branch, that public submit
4016
branch is used in the merge instructions. This means that a local mirror
4017
can be used as your actual submit branch, once you have set public_branch
4020
Mail is sent using your preferred mail program. This should be transparent
4021
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4022
If the preferred client can't be found (or used), your editor will be used.
4024
To use a specific mail program, set the mail_client configuration option.
4025
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4026
specific clients are "evolution", "kmail", "mutt", and "thunderbird";
4027
generic options are "default", "editor", "mapi", and "xdg-email".
4029
If mail is being sent, a to address is required. This can be supplied
4030
either on the commandline, or by setting the submit_to configuration
4033
Two formats are currently supported: "4" uses revision bundle format 4 and
4034
merge directive format 2. It is significantly faster and smaller than
4035
older formats. It is compatible with Bazaar 0.19 and later. It is the
4036
default. "0.9" uses revision bundle format 0.9 and merge directive
4037
format 1. It is compatible with Bazaar 0.12 - 0.18.

A merge directive provides many things needed for requesting merges:
4184
* A machine-readable description of the merge to perform
4186
* An optional patch that is a preview of the changes requested
4188
* An optional bundle of revision data, so that the changes can be applied

If --no-bundle is specified, then public_branch is needed (and must be
4193
up-to-date), so that the receiver can perform the merge using the
4194
public_branch. The public_branch is always included if known, so that
4195
people can check it later.
4197
The submit branch defaults to the parent, but can be overridden. Both
4198
submit branch and public branch will be remembered if supplied.
4200
If a public_branch is known for the submit_branch, that public submit
4201
branch is used in the merge instructions. This means that a local mirror

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
4208
default. "0.9" uses revision bundle format 0.9 and merge directive
