The graft file can contain comment lines and read_graft_line can
return NULL for such an input, which should be skipped by the

Just make it take over blame's place. Documentation and command
have all stopped mentioning "git-pickaxe". The built-in synonym
is left in the command table, so you can still say "git pickaxe",
but it probably is a good idea to retire it as well.
