cover git: support separate arg for `--config-env`'s value

Hi,

As pointed out by Ævar, the synopsis in the git(1) manpage was misdocumenting the syntax of the --config-env option. This patch series fixes it and also addresses the shortcoming that while most of the other options support both --git-dir=foo and --git-dir foo, --config-env only supported the former format.

I'm happy to drop the latter patch if it's generally seen as something that's not needed, but Ævar and Peff got a point in that it feels inconsistent with the other options.

PATCH 1/2 git.txt: fix synopsis of `--config-env` missing the equals sign

When executing git -h, then the --config-env documentation rightly lists the option as requiring an equals between the option and its
argument: this is the only currently supported format. But the git(1) manpage incorrectly lists the option as taking a space in between.

Fix the issue by adding the missing space.

PATCH 2/2 git: support separate arg for `--config-env`'s value

In reply to Patrick Steinhardt

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.

Yep. Likewise the weird extra space at the end of the string.
