# > One special feature of sed regular expressions is that they can default to the last regular expression used.
# > If a regular expression is empty, i.e., just the delimiter characters are specified, the last regular expression
# > encountered is used instead. The last regular expression is defined as the last regular expression used as part of
# > an address or substitute command, and at run-time, not compile-time. For example, the command “/abc/s//XXX/” will
# > substitute “XXX” for the pattern “abc”.
