The "comment-format" setting:

The global --comfmtflags command-line option (or alias --comment-format) overrides this setting.

Possible values are:

1

Activate the legacy comment printing format (default).

Or a bitwise combination of the following flags:

0

Activate the newer (non-legacy) comment printing format.

2

Trim leading and trailing CR and LF characters.

4

Trim leading and trailing white space characters.

8

Attempt to break lines on word boundaries.

16

Break lines before the original comment embedded in other text.

Note: To preserve line breaks, activate the newer (non-legacy) comment printing format (i.e. set to "0", or a combination not including "1").

Note: The options for timeline comments displayed on the web UI can be configured through the /setup_timeline web page.
