Comment (by mascguy):

 Replying to [comment:11 mascguy]:
 > FYI, for `libfmt8`, everything has been pushed down one level

 For consistency, I'll update `libfmt` to be similarly segregated.
 Otherwise, the headers may inadvertently be used, when both are installed.

 While the segregation changes are trivial, it'll take some time to tweak
 all dependents. More to follow.
