Usage of mime type in mk-origtargz

[Andreas Tille]

Hi Joachim,

I tried to fix a watch file or r-other-bio3d which you can find in

Vcs-Svn: svn://anonscm.debian.org/debian-med/trunk/packages/R/r-other-bio3d/trunk/

When trying this d/watch file with uscan version:

$ uscan --version | grep devscripts.*version
This is uscan, from the Debian devscripts package, version 2.14.5~bpo70+2

I get the following results:

$ uscan --verbose --force-download 
-- Scanning for watchfiles in .
-- Found watchfile in ./debian
-- In debian/watch, processing watchfile line:

Parameter ../download-bucket does not look like a tar archive or a zip file. at /usr/bin/mk-origtargz line 320.

It seems uscan is only respecting file names instead of using file to
detect the content of a file.  As far as I understood this should have
been implemented with the latest change but I might be wrong here.  This
also does not change if I add the '--rename' option.

When forcing a *.tar.gz extension to the download file via

   .*bio3d-v([-.0-9]+)
 
(hmmm, sorry folks this is a pure filenamemangle but I have no idea how
to inject the version string here)  I get:

$ uscan --verbose --force-download

I guess this is a sign that `file` or some Perl equivalent to obtain the
file content is not (yet ?) used.

Kind regards

      Andreas.

PS: Any hint for a better filenamemangle and also pgpsigurlmangle is
    welcome as well.
