DESCRIPTION
-----------
Look for specified patterns in the tracked files in the work tree, blobs
-registered in the index file, or blobs in given tree objects.
+registered in the index file, or blobs in given tree objects. Patterns
+are lists of one or more search expressions separated by newline
+characters. An empty string as search expression matches all lines.
CONFIGURATION
grep.lineNumber::
If set to true, enable '-n' option by default.
+grep.patternType::
+ Set the default matching behavior. Using a value of 'basic', 'extended',
+ 'fixed', or 'perl' will enable the '--basic-regexp', '--extended-regexp',
+ '--fixed-strings', or '--perl-regexp' option accordingly, while the
+ value 'default' will return to the default matching behavior.
+
grep.extendedRegexp::
- If set to true, enable '--extended-regexp' option by default.
+ If set to true, enable '--extended-regexp' option by default. This
+ option is ignored when the 'grep.patternType' option is set to a value
+ other than 'default'.

directory and its subdirectories.
-`git grep -e {apostrophe}#define{apostrophe} --and \( -e MAX_PATH -e PATH_MAX \)`::
+`git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
Looks for a line that has `#define` and either `MAX_PATH` or
`PATH_MAX`.
