[PATCH v3 0/9] icase match on non-ascii

Compared to v2

 - fix grep/pcre on utf-8 even in case is sensitive
 - peek at $LANG and friends anyway for utf-8 detection even
   when gettext support is not built in git
 - s/quote we quote/so we quote/ in 9/9
 - rename t7813, s/non-ascii/iso/

Nguyễn Thái Ngọc Duy (9):
  grep: allow -F -i combination
  grep: break down an "if" stmt in preparation for next changes
  grep/icase: avoid kwsset on literal non-ascii strings
  grep/icase: avoid kwsset when -F is specified
  grep/pcre: prepare locale-dependent tables for icase matching
  gettext: add is_utf8_locale()
  grep/pcre: support utf-8
  diffcore-pickaxe: "share" regex error handling code
  diffcore-pickaxe: support case insensitive match on non-ascii
