 As GNU sed manual points out, it uses 'I', not 'i', b/c GNU sed
 supports alternative syntax for 'i' where the text to be added follows
 after 'i' on the same line:
 
   In many other programming languages, a lower case 'i' is used for
   case-insensitive regular expression matching.  However, in 'sed'
   the 'i' is used for the insert command (*note insert command::).
   ...
 
   $ printf "%s\n" a b c | sed '/b/id'
   a
   d
   b
   c
 
 That's probably worth a mention in the new, fixed text.
