Merge branch 'nd/wildmatch'
Allows pathname patterns in .gitignore and .gitattributes files with double-asterisks "foo/**/bar" to match any number of directory hierarchies. * nd/wildmatch: wildmatch: replace variable 'special' with better named ones compat/fnmatch: respect NO_FNMATCH* even on glibc wildmatch: fix "**" special case t3070: Disable some failing fnmatch tests test-wildmatch: avoid Windows path mangling Support "**" wildcard in .gitignore and .gitattributes wildmatch: make /**/ match zero or more directories wildmatch: adjust "**" behavior wildmatch: fix case-insensitive matching wildmatch: remove static variable force_lower_case wildmatch: make wildmatch's return value compatible with fnmatch t3070: disable unreliable fnmatch tests Integrate wildmatch to git wildmatch: follow Git's coding convention wildmatch: remove unnecessary functions Import wildmatch from rsync ctype: support iscntrl, ispunct, isxdigit and isprint ctype: make sane_ctype[] const array Conflicts: Makefile

For example, "/{asterisk}.c" matches "cat-file.c" but not
"mozilla-sha1/sha1.c".
+Two consecutive asterisks ("`**`") in patterns matched against
+full pathname may have special meaning:
+
+ - A leading "`**`" followed by a slash means match in all
+ directories. For example, "`**/foo`" matches file or directory
+ "`foo`" anywhere, the same as pattern "`foo`". "**/foo/bar"
+ matches file or directory "`bar`" anywhere that is directly
+ under directory "`foo`".
+
+ - A trailing "/**" matches everything inside. For example,
+ "abc/**" matches all files inside directory "abc", relative
+ to the location of the `.gitignore` file, with infinite depth.
+
+ - A slash followed by two consecutive asterisks then a slash
+ matches zero or more directories. For example, "`a/**/b`"
+ matches "`a/b`", "`a/x/b`", "`a/x/y/b`" and so on.
+
+ - Other consecutive asterisks are considered invalid.
