[PATCH 5/7] userdiff/perl: match full line of POD headers

[Jonathan Nieder <jrnieder@gmail.com>]

The builtin perl userdiff driver is not greedy enough about catching
POD header lines.  Capture the whole line, so instead of just
declaring that we are in some "@@ =head1" section, diff/grep output
can explain that the enclosing section is about "@@ =head1 OPTIONS".
