Bug#866998: pgpmode=next/previous not working as expected?

Hi,

I don't think uscan should rephrase all ambiguous dpkg error messages.
If work is needed to be done, it's dpkg side.  But I don't think it is
needed.

Let me show...

Well, ... there could be all other dpkg error messages.  Just for example:

$ dpkg --compare-versions "1:-" gt 2; echo $?
dpkg: error: version '1:-' has bad syntax: revision number is empty
2
$ dpkg --compare-versions "1_" gt 2; echo $?
dpkg: warning: version '1_' has bad syntax: invalid character in version number
1
$ dpkg --compare-versions "a" gt 2; echo $?
dpkg: warning: version 'a' has bad syntax: version number does not start with digit
0
$ dpkg --compare-versions "-1-" gt 2; echo $?
dpkg: error: unknown option -1

Type dpkg --help for help about installing and deinstalling packages [*];
Use 'apt' or 'aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;

Options marked [*] produce a lot of output - pipe it through 'less' or 'more' !
2
$ dpkg --compare-versions "--" gt 2; echo $?
dpkg: error: --compare-versions takes three arguments: <version> <relation> <version>

Type dpkg --help for help about installing and deinstalling packages [*];
Use 'apt' or 'aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;

Options marked [*] produce a lot of output - pipe it through 'less' or 'more' !
2

All of these are useful error messages.

If you wish to know internals of uscan action for debug, uscan with the
--debug option produces a human readable report of uscan's execution
including internal variable states.

I don't think adding any more cosmetic complications are good or uscan.

I also think this is not-so badly ambiguous.  Many Debian documents have
this "version" ambiguity which we should all be familiar with as DD.

Of course, if you have a nice set of clean patch, it is welcomed.  (But
I don't want to make such patch.)
