The issue was that there was an empty line before the XML declaration, which
is not valid.

how_old() becomes a problem when we have a cache, because the relative dates
will get stalled in the cache.

This is makes a workaround by making how_old() return a string containing the
fixed date, which isn't quite nice but it will do the trick until a better
solution comes up.

This patch implements a very simple but effective cache, so darcsweb can avoid
regenerating everything all the time.

Based on an idea from Alexandre Rossi.

In multidir configuration entries, skip all the directories that don't have a
"_darcs" inside.

Check if the entry is a directory and doesn't begin with a dot.

Besides, sort it so the listing appears in predictable order.

This patch implements a special configuration entry called "multidir" that can
be useful when you have a lot of repositories in the same directory and don't
want to create an entry for each one.

This patch makes it simpler, because it skips displaying the full author name
and how long ago the changes were made; besides some simple fixes.

The rationale behind this is purely aesthetic: the author is already available
in the tooltip (and you should be able to tell anyway by its nickname), and
the "how long ago" was a bit distracting. All this is completely subjective, I
know, but I think these are "safe" settings.

In shade or zebra annotate modes, this patch displays a second
and third line of information in a contiguous single patch code block.

:First Line: ``DATE AUTHOR_SHORT_NAME`` (Same as before)
:Second Line: ``TIME RELATIVE_TIME``
:Third Line: ``FULL_AUTHOR_EMAIL``

All following lines in the code block are blank.

This patch adds two more annotate styles: zebra and shade.

Zebra alternates the line background colour according to the patch, just like
most CVS viewers do.

Shade is a lot more fun: it gives each patch a shade of a colour, the newer
the brighter, so newer patches (which are often the ones you're intrested in)
are easier to spot. It could use a little tuning on some constants to make it
look better, but it's pretty usable as is, and it can be done later if needed.
Thanks to Max Battcher for the idea.

Add a list of patches with their dates to the annotate object, because we'll
want to use them in patches to come. Also store the date in tuple format and
let the users do the conversion to text as they need to.

Yeah, I feel stupid creating a patch just for this, but my 80-column terminal
just hurts when I look at this line.

Add a column to the left of the annotate output, just before the line number,
to show the date (but not time) and author (in a short form).

Tabs need to be replaced with spaces to avoid problems displaying lines that
begin with tabs.

This patch implements a very simple function to do so, and modifices
print_blob() to use it.

Make the plain outputs use UTF8 too, as it's the only sane option.

This patch fixes some of the UTF8 handling in different annotate parts.

Accidentally, it also includes a small modification to show for each line of
the annotate the last modification time, date and author as a tooltip. It'd be
nice to put this in a different patch.

Finally!

popen4 call takes a mode parameter that should specify if the fds are text or
binary. Thanks to Gordon Heydon for reporting it.

This small changes makes darcsweb run properly under Windows.

Thanks to Gordon Heydon who reported the bug and tested the fix.

This patch adds support to allow you to specify the summary shown in the repo
list, as well as changing the default footer; all optional.

This is based on the patches sent by Zachary P. Landau and Remko Troncon.

The darcspath example now ends in 'bin/', to indicate that the path
is prepended to the 'darcs' command name.
