[JGIT PATCH 06/28] Initialize TextBuiltins with the repository before execution

["Shawn O. Pearce" <spearce@spearce.org>]

This way the default constructor used by the option parser does
not cause the output stream to allocate until we have chosen to
really work with this builtin command and have a repository for
it to read/write against.
