commit 5da6bb56e4aac67d4afbbbcf120f9a0969971006
Author: Bruno Le Floch <blflatex at gmail.com>

    Add test for https://github.com/latex3/latex2e/issues/351
    
    (Not sure why that issue was in our LaTeX2e tracker instead of in
    LaTeX3.)  This test purposefully does not show truncation per se,
    because that would require an annoying LuaTeX-specific tlg.  If
    the key name was longer the undefined control sequence would be
    pushed to the end of the line and end up being truncated by TeX.
