Subject: Do not wrap forceTLR in \L with babel and unicode engines
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=1e28965589bcf5ad85ed6d75ae2e59611989f78e;p=features.git

Do not wrap forceTLR in \L with babel and unicode engines

It does not seem to be needed, the \L macro is undefined, and there
does not seem to be an alternative.
