In filetype_extensions.conf the line (notice `*rc`)
`Conf=*.conf;*.ini;config;*rc;*.cfg;*.desktop;*.properties;`
overwrites (notice `.bashrc`)
`Sh=PKGBUILD;*.sh;configure;configure.in;configure.in.in;configure.ac;*.ksh;*.mksh;*.zsh;*.ash;*.bash;.bashrc;bash.bashrc;.bash_*;bash_*;*.m4;PKGBUILD;*profile;`
and therefore .bashrc is detected as being a Config file instead of a bash script.
