commit: fix unmodified message detection for the "--- >8 ----" magic
We need the raw editortext to be compared with the templatetext.
commit: update test to actually modify template text
We have a check for unmodified commit message (introduced by
bec1a579ebc4),
which should be enabled for the "--- >8 ---" magic but currently not.
pager: wrap ui._runpager
As discussed at [1], ui._runpager will be the new low-level API accepting a
pager command to actually run the pager. And ui.pager is the high-level API
which reads config directly from self.
This change is necessary for chgserver to override _runpager cleanly.

revset: add a followlines(file, fromline, toline[, rev]) revset
This revset returns the history of a range of lines (fromline, toline) of a
file starting from `rev` or the current working directory.
Added tests in test-annotate.t which already contains a reasonably complex
repository.
context: add a `blockancestors(fctx, fromline, toline)` function
This yields ancestors of `fctx` by only keeping changesets touching the file
within specified linerange = (fromline, toline).
Matching revisions are found by inspecting the result of `mdiff.allblocks()`,
filtered by `mdiff.blocksinrange()`, to find out if there are blocks of type
"!" within specified line range.
If, at some iteration, an ancestor with an empty line range is encountered,
the algorithm stops as it means that the considered block of lines actually
has been introduced in the revision of this iteration. Otherwise, we finally
yield the initial revision of the file as the block originates from it.
When a merge changeset is encountered during ancestors lookup, we consider
there's a diff in the current line range as long as there is a diff between
the merge changeset and at least one of its parents (in the current line
range).
