[PATCH 00/45] "struct pathspec" conversion and :(glob)

This series finishes off "struct pathspec" conversion that was started 2 years ago when this struct was added. In the end we can pass more information down the callchain than simply a series of strings. This makes it possible to add more pathspec "magic", the :(glob) in the end of this series is an example. This also changes --literal-pathspecs slightly, to not just make the pathspec literal, but to disable all magic.

Next step: introduction of :(icase) magic for case-insensitive matching (definitely won't take another 2 years as the groundwork is pretty much done).

Nguyễn Thái Ngọc Duy (45):
