Bug#744320: devscripts: dpkg-depcheck doesn't properly handle paths with ../'s when checking to see if the file is provided by an existing package

[William King]

Package: devscripts
Version: 2.14.1
Severity: normal

Dear Maintainer,

Was working to build a new debian package and determine the package dependencies with:
dpkg-depcheck -d ./configure

it failed to properly detect the package that provides files that were referenced with paths with ../../'s in them.

Adding a line to convert the file path to an abs_path() after confirming the file exists resolves the problem. Patch to follow shortly.
