diff --stat: enable limiting of the graph part
A new option --stat-graph-width=<width> can be used to limit the width of the graph part even is more space is available. Up to <width> columns will be used for the graph. If commits changing a lot of lines are displayed in a wide terminal window (200 or more columns), and the +- graph uses the full width, the output can be hard to comfortably scan with a horizontal movement of human eyes. Messages wrapped to about 80 columns would be interspersed with very long +- lines. It makes sense to limit the width of the graph part to a fixed value (e.g. 70 columns), even if more columns are available.

or 80 columns if not connected to a terminal, and can be
|
||||
overriden by `<width>`. The width of the filename part can be
|
||||
limited by giving another width `<name-width>` after a comma.
|
||||
The width of the graph part can be limited by using
|
||||
`--stat-graph-width=<width>`.
|
||||
By giving a third parameter `<count>`, you can limit the
|
||||
output to the first `<count>` lines, followed by `...` if
|
||||
there are more.
