tests: require regexes in unified tests to be marked with " (re)"

Consider this test:

  $ hg glog --template '{rev}:{node|short} "{desc}"\n'
  @  2:20c4f79fd7ac "3"
  |
  | o  1:38f24201dcab "2"
  |/
  o  0:2a18120dc1c9 "1"

Because each line beginning with "|" can be compiled as a regular
expression (equivalent to ".*|"), they will match any output.

Similarly:

  $ echo foo


The blank output line can be compiled as a regular expression and will
also match any output.

With this patch, none of the above output lines will be matched as
regular expressions. A line must end in " (re)" in order to be matched
as one.

Lines are still matched literally first, so the following will pass:

  $ echo 'foo (re)'
  foo (re)

  $ hg init t
  $ cd t

  $ echo foo > a
  $ hg add a

  $ hg commit -m "1"
