The "comment-format" setting:
Set the default options for printing timeline comments to the console.
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.
