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)
