[PATCH 09/10] t4213: test --function-name option

["David A. Dalrymple (and Bhushan G. Lodha)" <dad-bgl@mit.edu>]

From: "Bhushan G. Lodha & David A. Dalrymple" <dad-bgl@mit.edu>

This test builds a sample C file, adding and removing functions, and
checks that the right commits are filtered by --function-name matching.
