basename: suffix argument did nothing

[mknos]

• The pod manual mentioned that the optional suffix could be a normal string or a regex
• Follow the standards document and implement string match, being careful to match only at the end of the string, and not to match the entire string (after prefix is stripped) [1]
• Remove reference to regex suffix in pod
• Bump version

  %perl basename `pwd`/a.c  # test1: no suffix
  %perl basename `pwd`/a.c eyy.si  # test2: no match for suffix
  %perl basename `pwd`/a.c a.c  # test3: match consumes all of remaining string so it is ignored
  %perl basename `pwd`/a.c .c   # test4: file extension .c is removed
