tests: various fixes for new unified test pattern format [ original upstream message ]

tests: add glob matching for unified tests This adds a " (glob)" marker that works like a simpler version of (re): "*" is converted to ".*", and "?" is converted to ".". Both special characters can be escaped using "\", and the backslash itself can be escaped as well. Other glob-style syntax, like "**", "[chars]", or "[!chars]", isn't supported. [ original upstream message ]

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) [ original upstream message ]

tests: ensure regexes match to the end of the string Regular expressions in the test suite are currently written assuming that you need a trailing ".*" to avoid matching to the end. Instead of matching regular expressions using "^pattern", this patch makes matching more restrictive by matching "^pattern$". [ original upstream message ]

tests: don't match blank output lines as regexes in unified tests Currently, the following unified test will pass: $ echo foo A blank output line (a line containing just two spaces) will match any output. The patch modifies the unified test runner to ignore empty strings strings when do regular expression matching. [ original upstream message ]

merge: suggest 'hg up -C .' for discarding changes, not 'hg up -C' Without specifying the parent revision of the working copy, users will update to tip, which is most likely the other head they were trying to merge, not the revision they were at before the merge. [ original upstream message ]
