Messages `<unknown>:119: SyntaxWarning: invalid escape sequence '\.'` and similar are emitted for a package to check.

Ahoj,

I have the following package: rtl88xxau-aircrack-dkms-git-r1298.b44d288-1-x86_64.pkg.tar (built from ↗ this AUR package).

When I run namcap on it, it emits messages like
<unknown>:119: SyntaxWarning: invalid escape sequence '\.':
