Bug#731537: [uscan] fails to rename downloaded upstream tar ball if d/copyright is not machine-readable

[Axel Beckert]

Package: devscripts
Version: 2.13.5
Severity: normal

Since recently (probably since the recent uscan changes), uscan still
downloads upstream tar balls, but fails to rename them if
debian/copyright is not in the machine-readable format.

Example:

libstring-random-perl $ uscan --verbose --download-current-version
-- Scanning for watchfiles in .
-- Found watchfile in ./debian
-- In debian/watch, processing watchfile line:
   opts="uversionmangle=s/^v(\d)/$1/;s/^\.(\d)/0.$1/" https://metacpan.org/release/String-Random/   .*/String-Random-v?(\d[\d.-]+)\.(?:tar(?:\.gz|\.bz2)?|tgz|zip)$
-- Found the following matching hrefs:
