Re: [PATCH] git-remote: list branches in vertical lists

[Johannes Sixt <j.sixt@viscovery.net>]

From: Johannes Sixt <j6t@kdbg.org>

Previously, branches were listed on a single line in each section. But
if there are many branches, then horizontal, line-wrapped lists are very
inconvenient to scan for a human. This makes the lists vertical, i.e one
branch per line is printed.

Since "git remote" is porcelain, we can easily make this
backwards-incompatible change.

Here we go.

Note the new email address, too. I'm afraid the old one, @telecom.at, goes
out of service by the end of the year.
