readline6-6.3-bp160.1.8

- Rename readline-6.2-endpw.dif to readline-6.2-endpw.nodif

- Fix escaping of commented out patch: with RPM 4.20, %patch
  becomes a standard, expandable macro, that can span more than one
  line. Commenting out with #%patch can thus lead to invalid
  results.

- Use %patch -P N instead of deprecated %patchN.

- Replace transitional %usrmerged macro with regular version check (boo#1206798)

- Move to /usr for UsrMerge (boo#1191091)

- Guess what ... shut up the licensedigger and add COPYING

- Replace boilerplate summary

- create package as compat package for libreadline6
