Bug#603881: pbuilder: get_source_control_field: fails to parse debian/control with leading comment-block

[Eric Pozharski]

Package: pbuilder
Version: 0.199
Severity: important
Tags: patch

atk1.0_1.30.0-1 has a leading block of comments in debian/control file.
'pbuilder' then fails to get Build-Depends (actually any other too) from
such file.

Attached patch works with or without leading comment-block.  That
comment-block could or not have separating empty line.  It fails with
multiple separating empty lines.  Also if there's no comment-block while
empty-line is present then it fails 'get_source_control_field' too.

As of 'important'.  Look, atk1.0 is in testing.  It has been
successfully built at 04Apr2010.  Thus debian build system supports such
comment-blocks.  Please fix.
