Bazaar VCS support
 
I'm really sorry about the delay replying to this. Some how, I did not
see your reply till today.

Ok, After reading PKGBUILD.5.txt again, I see the inconsistency. I've
updated the patch so that the revisionspec fragment would be specified
like this, so that is consistent with the others:

url#revision=[any bzr revisionspec]
url#revision=3
url#revision=tag:mytag

Done.

That would not work for Bazaar. This is why:

Unlike git/hg, bzr urls refer to a branch, not a repo.

When you do a bzr branch/pull, it only fetches revisions that are descendants of the branch tip into the local repo. Hence, doing a branch/pull without specifying the fragment revision, it is possible that the fragment revision is not available. Here is an example revision dag for which this would happen:

fragment revision = tag:mytag

c (branch tip
| b (tag:mytag
|/
a

Done.

Almost there! Fairly minor comments below.

Thanks for the explanation of the different behaviour of the bzr
checkout compared to git, hg, etc.

Please change this (and throughout the patch) to keep protocols in
alphabetical order.

This has been changed in the other vcs functons on my git branch to
${netfile#*#} as that allows the fragment to contain a "#" character.

Strings starting with a "-" can lead to issues... Changes this to:
revision=('-r-1')

I guess $revisionspec should be $revision? And with comment above it
will be $(revision[@])
