Bug#841254: devscripts[bts]: cache 'bts status' output

[Daniel Shahaf]

Package: devscripts
Version: 2.16.8
Severity: wishlist

Dear Maintainer,

I propose to add to bts(1) a --cache-mode that caches 'bts status' output.

Use-case: I've taught zsh completion to show the bug subjects alongside
the bug numbers¹, but the implementation parses the <title> attribute
from the HTML cache files using Perl, and I'd like to simplify it to
parse 'bts status' output instead, without requiring online access.

Cheers,

Daniel
