Subject: GNU awk regex fix
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=6eedd701a8aed8fa8b0f753b97bd0671bcc14891;p=users%2Fdwmw2%2Fvpnc-scripts.git

GNU awk regex fix

The character `#` does not need to be backslash-escaped in awk regexes, and
GNU awk v5.1.0 complains about these regexes (first added in 3885f8bb).

Fixes #17
