Hi cperl-mode can't call perldocs for functions with a hyphen anymore like "-e" or "-X" (cperl-perldoc "-e") or "M-x cperl-perldoc RET -e" result to "error in process sentinel: Man-bgproc-sentinel: Can't find the -e manpage" But perldoc -f -e works fine in the shell, and as far as I can see from the sources of cperl-mode "-e" this case is covered to be mapped on the -f switch. Tested on 23 and 22 from two different users on different continents.
