[PATCH] git-fast-import.txt: clarify that multiple merge commits are allowed

[Elijah Newren]

The grammar for commits used a '?' rather than a '*' on the `merge`
directive line, despite the fact that the code allows multiple `merge`
directives in order to support n-way merges.  In fact, elsewhere in
git-fast-import.txt there is an explicit declaration that "an unlimited
number of `merge` commands per commit are permitted by fast-import".
Fix the grammar to match the intent and implementation.
