The invocation instructions for the copy-libev example are a bit too wide.
The obvious wrapping
./copy-ev \
nbd+unix:///?socket=/tmp/src.sock \
nbd+unix:///?socket=/tmp/dst.sock
is not desirable in a C-language comment, because the C standard places
line splicing before comment squashing (translation phases #2 and #3,
respectively). Therefore use shell variables.
While at it, fix a small typo (from commit 6be6a9029abb, "examples: Add
example for integrating with libev", 2021-03-01): the executable is called
"copy-libev", not "copy-ev".
