[oe] should indent recipe use "${prefix}" instead of "/usr"?

[Robert P. J. Day]

  just noticed that ./meta-oe/recipes-extended/indent/indent_2.2.12.bb
on master branch contains the line:

  FILES_${PN}-doc += "/usr/doc/indent/indent.html"

should that not properly read:

  FILES_${PN}-doc += "${prefix}/doc/indent/indent.html"

or am i misreading something?
