 	confusion and troubles with script usage, aliases that
 	hide existing Git commands are ignored. Arguments are split by
 	spaces, the usual shell quoting and escaping is supported.
 	A quote pair or a backslash can be used to quote them.

+Note that the first word of an alias does not necessarily have to be a
+command. It can be a command-line option that will be passed into the
+invocation of `git`. In particular, this is useful when used with `-c`
+to pass in one-time configurations or `-p` to force pagination. For example,
+`loud-rebase = -c commit.verbose=true rebase` can be defined such that
+running `git loud-rebase` would be equivalent to
+`git -c commit.verbose=true rebase`. Also, `ps = -p status` would be a
+helpful alias since `git ps` would paginate the output of `git status`
+where the original command does not.
++
 If the alias expansion is prefixed with an exclamation point,
 it will be treated as a shell command.  For example, defining
-"alias.new = !gitk --all --not ORIG_HEAD", the invocation
+`alias.new = !gitk --all --not ORIG_HEAD`, the invocation
-"git new" is equivalent to running the shell command
+`git new` is equivalent to running the shell command
-"gitk --all --not ORIG_HEAD".  Note that shell commands will be
+`gitk --all --not ORIG_HEAD`.  Note that shell commands will be
 executed from the top-level directory of a repository, which may
 not necessarily be the current directory.
