Subject: Add --version and -version as aliases for -V
X-Git-Tag: working-ls180~852^2
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b76b02358439cd04ed5cad5cb889e8b43c801ac1;p=yosys.git

Add --version and -version as aliases for -V

The flag --version is commonly accepted by command line tools.
The code for the version flags added here matches the pattern used for
the help flag aliases, for consistency.

Fixes #1612
