templater: introduce one-pass parsing of nested template strings
Instead of re-parsing quoted strings as templates, the tokenizer can delegate
the parsing of nested template strings to the parser. It has two benefits:
1. syntax errors can be reported with absolute positions
2. nested template can use quotes just like shell: "{"{rev}"}"
It doesn't sound nice that the tokenizer recurses into the parser. We could
instead make the tokenize itself recursive, but it would be much more
complicated because we would have to adjust binding strengths carefully and
put dummy infix operators to concatenate template fragments.
Now "string" token without r"" never appears. It will be removed by the next
patch.

When they occur, it reverts *all* changes and moves forward, letting the conflict resolving patch fix collisions. Unfortunately, non-conflicting changes, like the addition of the "c" file in p1.1 patch are reverted too. Just to say that manifest not listing "c" here is a bug. $ cd .. $ hg convert darcs-repo darcs-repo-hg initializing destination darcs-repo-hg repository scanning source... sorting... converting... 4 p0 3 p1.2 2 p1.1 1 p2 0 p3 $ hg log -R darcs-repo-hg -g --template '{rev} "{desc|firstline}" ({author}) files: {files}\n' "$@" 4 "p3" (test@example.org) files: dir/d dir/d2 dir2/d f ff 3 "p2" (test@example.org) files: a dir/d dir/d2 f 2 "p1.1" (test@example.org) files: 1 "p1.2" (test@example.org) files: a b 0 "p0" (test@example.org) files: a $ hg up -q -R darcs-repo-hg $ hg -R darcs-repo-hg manifest --debug 7225b30cdf38257d5cc7780772c051b6f33e6d6b 644 a 1e88685f5ddec574a34c70af492f95b6debc8741 644 b 37406831adc447ec2385014019599dfec953c806 644 dir2/d b783a337463792a5c7d548ad85a7d3253c16ba8c 644 ff #if no-outer-repo try converting darcs1 repository $ hg clone -q "$TESTDIR/bundles/darcs1.hg" darcs $ hg convert -s darcs darcs/darcs1 2>&1 | grep darcs-1.0 darcs-1.0 repository format is unsupported, please upgrade #endif
