Wildcards in the pattern such as `*` or `?` are treated
as literal characters.
+
+glob;;
+ Git treats the pattern as a shell glob suitable for
+ consumption by fnmatch(3) with the FNM_PATHNAME flag:
+ wildcards in the pattern will not match a / in the pathname.
+ For example, "Documentation/{asterisk}.html" matches
+ "Documentation/git.html" but not "Documentation/ppc/ppc.html"
+ or "tools/perf/Documentation/perf.html".
++
+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.
++
+Glob magic is incompatible with literal magic.

Currently only the slash `/` is recognized as the "magic signature",
