Try either of:
wc -lw -- -l
wc -lw ./-l
This is not a bug in wc. Rather, it is a FAQ:
https://www.gnu.org/software/coreutils/faq/coreutils-faq.html#I-have-a-file-called-_002d_002dhelp_002e-How-do-I-remove-it_003f
And like most utilities, using an explicit -- to mark the end of
options, or spelling your file name with a leading ./ so that it can't
be confused with an option, will do the trick.
Therefore, I'm closing this as not a bug, although you should feel free
to add any further comments or questions to this thread.
