Subject: [PATCH 2/2] git: support separate arg for `--config-env`'s value
Date: Mon, 19 Apr 2021 17:56:55 +0200
Message-ID: <d52db89bc2f40a9df5e9fafe4e1bb8c173a7f45f.1618847606.git.ps@pks.im> (raw)
In-Reply-To: <cover.1618847606.git.ps@pks.im>


[-- Attachment #1: Type: text/plain, Size: 2693 bytes --]

While not documented as such, many of the top-level options like
`--git-dir` and `--work-tree` support two syntaxes: they accept both an
equals sign between option and its value, and they do support option and
value as two separate arguments. The recently added `--config-env`
option only supports the syntax with an equals sign.

Mitigate this inconsistency by accepting both syntaxes and add tests to
verify both work.
