Re: [PATCH 2/5] t4211: demonstrate empty -L range crash

You could avoid the 'cat' here and patch in 4/5 by doing $(wc -l <b.c).

Correct.

(Side question: the test suite is full with similar constructs, i.e.
redirecting file contents to stdin, but why not just use wc -l b.c,
i.e. let wc open the file?)

"wc -l <b.c" is the correct form for the purpose of these tests;
otherwise you will see the filename in the output, and you need to
somehow strip it if you are only interested in the line count.
