Simplify the perldelta howto by using Git features

`git-log' can generate a list of authors without perl's help and
`git-diff` can produce a diffstat without diffstat(1).

 You can find the list of committers and authors by:
 
-  % git log v5.11.1..HEAD | perl -nlwe '$seen{$1}++ if /^Author: ([^<]*)/; END { print for sort keys %seen }'
+  % git log --pretty='format:%an' v5.11.1..HEAD | sort | uniq
 
 And how many files where changed by:
 
-  % git diff v5.11.1..HEAD | diffstat
+  % git diff --stat=200,200 v5.11.1..HEAD
