[issue623] Make hgweb annotate link to target line numbers

[Thomas Arendsen Hein]

New submission from Thomas Arendsen Hein <thomas at intevation.de>:

Moved from issue506 (annotation enhancement to show line-no at first appearance):

Extend hgweb annotation to be able to jump to the correct line in the target
file, e.g. line 83 in current mercurial/localrepo.py was created in changeset
d7df759d0e97 in file mercurial/hg.py line 337, therefore line 83 in
http://hg.intevation.org/mercurial/crew/annotate/8e503fa54d2d/mercurial/localrepo.py
should link to something like
http://hg.intevation.org/mercurial/crew/annotate/d7df759d0e97/mercurial/hg.py#337
(so only the #337 part and the corresponding anchors are missing)

Calculating the line numbers costs about 20-25% additional wallclock time and
annotate already isn't the fastest operation. But I think this way it will be
far more useful.

So I see two options:
- Have it always enabled
- Provide a [web] config option to disable it permanently

If this info is not calculated by default but the user has to click on "annotate
with line numbers", then you will often need 125% additional time (instead of
25%) everytime a user tries to track down a certain line in the history.

I'd vote for "always enabled", because it is simpler and people having limited
CPU would already suffer from annotation, too.
