test-arbitraryfilectx: stabilize for Windows

Previously, the second last test (context.arbitraryfilectx(..)) returned True on
Windows.  I changed the repo setup sequence to import a patch, so that way the
repo would have a proper symlink.  That made the last test fail, since it is
comparing files in wdir(), one of which is not the expected symlink.

Apparently the (feature !) line matching doesn't work well with (no-eol), so I
had to conditionalize the test instead of the output.

test command parsing and dispatch

  $ hg init a
  $ cd a

Redundant options used to crash (issue436):
  $ hg -v log -v
  $ hg -v log -v x

  $ echo a > a
  $ hg ci -Ama
  adding a

Missing arg:

  $ hg cat
  hg cat: invalid arguments
  hg cat [OPTION]... FILE...
  
  output the current or given revision of files
  
  options ([+] can be repeated):
  
   -o --output FORMAT       print output to file with formatted name
   -r --rev REV             print the given revision
      --decode              apply any matching decode filter
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns
  
  (use 'hg cat -h' to show more help)
