[PATCH 05/17] Documentation: add missing quotes to "git grep" examples

[Jonathan Nieder <jrnieder@gmail.com>]

Without an indication to the contrary, Asciidoc puts 'quoted
text' in italics, making the output look like this:

	git grep time_t -- *.[ch]
	    Looks for time_t in all tracked .c and .h
	    files in the working directory and its subdirectories.

	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.

In the first example, the *.[ch] argument needs to be protected from
the shell, or else it will only match files in the current directory.
The second example has a stray backslash.
