[PATCH v4 00/13] Column display again

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Reroll of v3 [1]. This series adds support for column display like
"ls". "git branch", "git tag -l" and "git status"'s untracked files
can now be displayed in columns. There's also "git-column" to help
do the layout for commands that are not aware of column display. In
fact git-tag uses it this way.

I've been thinking of supporting the layout where a cell's content can
occupy more than one cell. It'll make better use of space when there
are a few long entries. Something like this:

abc    def    ghk
longlonglong  short
again  here   now

"git status" may benefit when you have untracked files in some deep
directories.

"ls -R" layout is also an option ("branch -r" and ls-files will
benefit due to dense tree output). But these ideas will have to wait
until later.

Compared to v3, it has "git status" support, the return of git-column,
and column.* conf vars.
