shortest: make {shortest("fffffffff")} work again

{shortest("fffffffff")} should shorten it to the shortest unambiguous
prefix for the working directory. It used to do that until I broke it
in 7b2955624777 (scmutil: make shortesthexnodeidprefix() take a full
binary nodeid, 2018-04-14), when we started returning the full hex
nodeid for any working directory prefix shorter than 40 hex
digits. This patch fixes it by catching WdirUnsupported
specifically.

 Set up repository for non-ascii encoding tests:
 
   $ hg init nonascii
   $ cd nonascii

 json filter should try round-trip conversion to utf-8:

   "\u00e9"
   $ HGENCODING=ascii hg log -T "{desc|json}\n" -r0
   "non-ascii branch: \u00e9"
 
 json filter takes input as utf-8b:
 
   $ HGENCODING=ascii hg log -T "{'`cat utf-8`'|json}\n" -l1
   "\u00e9"
   $ HGENCODING=ascii hg log -T "{'`cat latin1`'|json}\n" -l1

 Test 'graphwidth' in 'hg log' on various topologies. The key here is that the
 printed graphwidths 3, 5, 7, etc. should all line up in their respective
 columns. We don't care about other aspects of the graph rendering here.

 The point of graphwidth is to allow wrapping that accounts for the space taken
 by the graph.

 Something tricky happens when there are elided nodes; the next drawn row of
 edges can be more than one column wider, but the graph width only increases by
 one column. The remaining columns are added in between the nodes.
