[PATCH v2 09/11] fast-import: remove unmaintained duplicate documentation

[Elijah Newren <newren@gmail.com>]

fast-import.c has started with a comment for nine and a half years
re-directing the reader to Documentation/git-fast-import.txt for
maintained documentation.  Instead of leaving the unmaintained
documentation in place, just excise it.
