[PATCH v5 00/12] nd/wildmatch

This version splits fnmatch/wildmatch tests separately in t3070 and disables a lot more fnmatch tests. It also fixes the "cd .." in t0003 test and a comment in front of dowild(). No functional changes.

Nguyễn Thái Ngọc Duy (12):
  ctype: make sane_ctype[] const array
  ctype: support iscntrl, ispunct, isxdigit and isprint
  Import wildmatch from rsync
  wildmatch: remove unnecessary functions
  Integrate wildmatch to git
  t3070: disable unreliable fnmatch tests
  wildmatch: make wildmatch's return value compatible with fnmatch
  wildmatch: remove static variable force_lower_case
  wildmatch: fix case-insensitive matching
  wildmatch: adjust "**" behavior
  wildmatch: make /**/ match zero or more directories
  Support "**" wildcard in .gitignore and .gitattributes
