[PATCH] D40288: [clang-format] Add option to group multiple #include blocks when sorting includes

2017-11-21 Thread Krzysztof Kapusta via Phabricator via cfe-commits 
KrzysztofKapusta created this revision.
KrzysztofKapusta added a project: clang-tools-extra.
Herald added a subscriber: klimek.

This patch allows grouping multiple #include blocks together and sort all 
includes as one big block.
Additionally, sorted includes can be regrouped after sorting based on 
configured categories.
