M-x man should know that "->" can't be part of a man page name.
(In fact "->" even displays as one character.) so M-x man should think
twice, and back off, so that when the cursor is upon the word UserAgent,
my $ua = LWP::UserAgent->new(...
and one types M-x man, instead of
Manual entry (default LWP::UserAgent-):
it should prompt with
Manual entry (default LWP::UserAgent):

Removing `-' from the end of the default value could be
fixed in `Man-default-man-entry' by this patch:
