The command calls

(isearch--yank-char-or-syntax '(?w) 'forward-word arg)

so I guess this means that "." has word syntax in Man buffers, but ","
doesn't?

I guess that makes sense -- you can have stuff like "foo.bar" that
should be considered a single "word", but I agree that it doesn't make
much sense to have a terminating "." be part of a word.

I'm not sure how to fix that, though -- switch isearch-yank-word-or-char
to something like ffap instead of using syntax classes?
