+-e::
+       The next parameter is the pattern. This option has to be
+       used for patterns starting with - and should be used in
+       scripts passing user input to grep.  Multiple patterns are
+       combined by 'or'.
+
+--and | --or | --not | ( | )::
+       Specify how multiple patterns are combined using boolean

+       higher precedence than `--or`.  `-e` has to be used for all

        Search blobs in the trees for specified patterns.

+       Looks for a line that has `#define` and either `MAX_PATH` or
