The output of "bzr log" seems to have changed a bit, so we change the
parsing accordingly. This has not been tested with earlier versions of
bzr.
Several problems seemed to occur, all in the bzr_log subroutine:
1. The @infos list would contain an empty hash, which would confuse the
rest of the program.
2. This was because bzr_log would push an empty anonymous hash to the
list whenever it thought a new record would start.
3. However, a new record marker (now?) also happens at th end of bzr log
output.
4. Now we collect the record to a hash that gets pushed to the list only
if it is not empty.
5. Also, sometimes bzr log outputs "revno: 1234 [merge]", so we catch only
the revision number.
6. Finally, there may be non-headers at the of the output, so we ignore
those.
For a while, I was avoiding capitalizing ikiwiki at the beginning of a
sentence. I now think that's a bad idea (unless explicitly referring to
the `ikiwiki` command). Still, I don't go all the way and always cap it,
as a proper noun. That would make the logo look bad. ;)
I also tend to avoid capping it as IkiWiki, except when referring to the
perl internals, which do use that capitalization. (Too late to change
that.) However, it's also reasonable to do so in a WikiLink, as a nod to
historical camelcase wikis.
Colons are not allowed at the start of urls, because it can be interpreted
as a protocol, and allowing arbitrary protocols can be unsafe
(CVE-2008-0809). However, this check was too restrictive, not allowing
use of eg, "video.ogv?t=0:03:00/0:04:00" to seek to a given place in a
video, or "somecgi?foo=bar:baz" to pass parameters with colons.
It's still not allowed to have a filename with a colon in it (ie
"foo:bar.png") -- to link to such a file, a fully qualified url must be
used.
