Subject: [PATCH] autoupdater: consider end of string smaller than all
 characters except for '~'

This fixes ordering for the following patterns:

* 1.0 < 1.0a
* 1.0a < 1.0ab
* 1.0a < 1.0a1

Note that trailing zeros are still ignored (1.0 == 1., 1test0 == 1test),
which matches the behaviour of dpkg and opkg.
