Merge branch 'zj/diff-stat-dyncol'
By Zbigniew Jędrzejewski-Szmek (8) and Junio C Hamano (1) * zj/diff-stat-dyncol: : This breaks tests. Perhaps it is not worth using the decimal-width stuff : for this series, at least initially. diff --stat: add config option to limit graph width diff --stat: enable limiting of the graph part diff --stat: add a test for output with COLUMNS=40 diff --stat: use a maximum of 5/8 for the filename part merge --stat: use the full terminal width log --stat: use the full terminal width show --stat: use the full terminal width diff --stat: use the full terminal width diff --stat: tests for long filenames and big change counts

Generate a diff using the "histogram diff" algorithm.
--stat[=<width>[,<name-width>[,<count>]]]::
- Generate a diffstat. You can override the default
- output width for 80-column terminal by `--stat=<width>`.
- The width of the filename part can be controlled by
- giving another width to it separated by a comma.
+ Generate a diffstat. By default, as much space as necessary
+ will be used for the filename part, and the rest for the graph
+ part. Maximum width defaults to terminal width, 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>` (affects all commands generating
+ a stat graph) or by setting `diff.statGraphWidth=<width>`
+ (does not affect `git format-patch`).
By giving a third parameter `<count>`, you can limit the
- output to the first `<count>` lines, followed by
- `...` if there are more.
