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)
