Could we add a --bpo NUMBER parameter to blurb add command?
This parameter would be used by for the template of blurb and would fill the .. bpo: NUMBER in the template.

why? when I create a branch for an issue, I use the number of the issue from bpo and I create a branch with this number.

Attention: I use the fish shell and not bash/zsh

for the checkout

> git checkout -b bpo-12345

> ./configure --prefix=$PWD-(git rev-parse --abbrev-ref HEAD) --with-pydebug
> make -j 4
> make install

I can get the issue number via git rev-parse --abbrev-ref HEAD | string sub --start=5
example:

> git rev-parse --abbrev-ref HEAD
bpo-12345
> git rev-parse --abbrev-ref HEAD | string sub --start=5
12345

and I would like to pass the bpo number on the command line like that:

> blurb add --bpo (git rev-parse --abbrev-ref HEAD | string sub --start=5)

Of course, maybe we could do the same thing for the section and the paragraph.

Example:

blurb add --bpo 12345 --section Documentation "Travis can build the documentation with the doctest. Contributed by Awesome Contributor".
