Bug#847944: pbuilder: get_source_control_field doesn't accept preceding comment

[Daniel Drake]

Package: pbuilder
Version: 0.226.1
Severity: important

The change made in bug #694404 introduce a regression.
pbuilder-satisfydepends-classic can no longer detect the Build-Depends if
it is preceded by a comment, e.g.

Source: my package
#foo
Build-Depends: debhelper (>= 9)

In this case no build dependencies are detected.
