[PATCH 00/21] "struct pathspec" conversion

This is another step towards the pathspec unification. This series introduces a get_pathspec() alternative: parse_pathspec(). The new function intializes struct pathspec directly. Many builtin commands (except mv) are converted to use this function. As a result, struct pathspec is used from the start for many commands.

The next step would be dealing with pathspec manipulation code blocks that use "raw" field, init_pathspec or get_pathspec(). add.c, dir.c, rm.c and mv.c are hot places. And perhaps move pathspec code from dir.c and setup.c to pathspec.c after as/check-ignore enters "master".

This series shares a patch (the first one) with nd/pathspec-wildcard. I put the patch in the series to avoid dependency.

This series also disables wildcards in the prefix part, but it's only effective in combination with nd/pathspec-wildcard. And of course it's not fully effective until all "raw" use is eliminated.

Nguyễn Thái Ngọc Duy (21):
  pathspec: save the non-wildcard length part
  Add parse_pathspec() that converts cmdline args to struct pathspec
  pathspec: make sure the prefix part is wildcard-clean
  Export parse_pathspec() and convert some get_pathspec() calls
