"hg import" can't handle multiple changesets per file

If you do "hg export 1 2 3 > file.patch", file.patch will contain a set
of hg changesets in exported form, including the hg header comment
before each.  However, "hg import file.patch" will ignore all but the
first header, and treat the entire file as a representation of that one
changeset.  In my case, this caused three large changesets to be
committed as one changeset, amusingly titled "formatting fixes". :)
