all --dehs output goes to STDOUT
all other output including verbose output goes to STDERR if --dehs is
used.

So use 2>/dev/null.  Having verbose output available for -dehs is really
good for debug etc.  In script, invoke uscan with 2>/dev/null

I have already killed almost all verbose output in VCS.  So default
output is readuced much more for VCS

 stable-bpo   2.16.1~bpo8+1
 testing      2.16.1

These did not address all the regressions caused by the major changes 
happened at 2.15.10

PENDING FIXES are
  [ Osamu Aoki ]
  * uscan:
    + Print proper warnings for bad rules.  Closes: #814049
    + Fix glitches around rules such as "s<...> <...>g" and add their
      tests.
    + Reactivate --no-verbose mode.  Closes: #815645
    + Fix --destdir for version 4.  Closes:#814686
    + Always use uscan_warn and uscan_die.
    + Die if the action script fails.  Closes: #810976

For --dehs, "Always use uscan_warn and uscan_die" is important.

I guess we need to wait for James McCoy to upload new version.

As for the current VCS code:
 $ uscan --dehs --report 2>/dev/null
<dehs>
<package>s3ql</package>
<debian-uversion>2.15+dfsg</debian-uversion>
<debian-mangled-uversion>2.15+dfsg</debian-mangled-uversion>
<upstream-version>2.17.1+dfsg</upstream-version>
<upstream-url>https://bitbucket.org/nikratio/s3ql/downloads/s3ql-2.17.1.tar.bz2</upstream-url>
<status>newer package available</status>
<messages>Not downloading upstream package: s3ql-2.17.1.tar.bz2
</messages>
</dehs>


Status report good.
No warnings to indicate there were no scanning errors.
So I see no problerm.
