[PATCH 4/4] Read author names and emails from a file

[Karl Hasselström <kha@xxxxxxxxxxx>]

Read a file with lines on the form

  username User's Full Name <email@xxxxxxxxxx>

and use "User's Full Name <email@xxxxxxxxxx>" as the GIT author and
committer for Subversion commits made by "username". If encountering a
commit made by a user not in the list, abort.
