Your reply reminds me of two ideas that bug me a lot, or I have been trying to catch to handle fasta files. 1) Use some sort of index (hashing? FM-index?); 2) use suffix array, tree or trie to do the job. I'm trying to get example code by starting from what I have.

GIT-WRITE-TREE(1)						    Git Manual							 GIT-WRITE-TREE(1)

NAME
git-write-tree - Create a tree object from the current index SYNOPSIS
git write-tree [--missing-ok] [--prefix=<prefix>/] DESCRIPTION
Creates a tree object using the current index. The name of the new tree object is printed to standard output. The index must be in a fully merged state. Conceptually, git write-tree sync()s the current index contents into a set of tree files. In order to have that match what is actually in your directory right now, you need to have done a git update-index phase before you did the git write-tree. OPTIONS
--missing-ok Normally git write-tree ensures that the objects referenced by the directory exist in the object database. This option disables this check. --prefix=<prefix>/ Writes a tree object that represents a subdirectory <prefix>. This can be used to write the tree object for a subproject that is in the named subdirectory. AUTHOR
