[PATCH/WIP 00/10] Fancy pathspec stuff

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

I wanted to see how new pathspec feature can be implemented after
nd/parse-pathspec, mainly to see if nd/parse-pathspec needs fixing.
It's nowhere near 'pu' quality but may be interesting for some people.

It does:

- introduce :q/.../ syntax in addition to :(...), which always
  requires quoting in bash

- separate prefix part from the rest of pathspec, allowing it to be
  treated differently (e.g. prefix is matched exactly regardless
  pathspec magic)

- implement :(glob) using wildmatch (i.e. incompatible with the
  wildcards that current pathspec uses)

- implement :(icase) -- with bugs

- implement :(literal), similar to --literal-pathspecs

That's all my spam for today.

Nguyễn Thái Ngọc Duy (10):
  pathspec: allow to use alternate char for quoting long magic mnemonic
  parse_pathspec: make sure the prefix part is wildcard-free
  pathspec: support :(literal) syntax for noglob pathspec
  parse_pathspec: save prefix information
  pathspec: prepare for :(glob)path syntax
  Enable :(glob)path syntax for a lot of commands
  parse_pathspec: accept :(icase)path syntax
  common_prefix/read_directory: treat PATHSPEC_ICASE like wildcards
  pathspec: support icase in match_pathspec_depth and
    tree_entry_interesting
  Enable ls-files and ls-tree for testing PATHSPEC_ICASE
