Config defaults in manpage

[Massimo-B]

Please describe the defaults for all the options in the man-page like the following, if they are not specified:

• -o dir_cache=BOOL
• -o dcache_max_size=N
• -o dcache_clean_interval=N
• -o max_conns=N

Then some questions which might be better go into separate tickets if there more to explain about...: I'm usually manually calling sshfs as user, not using /etc/fstab. Is there any configuration file for all the settings? I was always using -o cache=yes since years and noticed now it doesn't exist. sshfs does not complain, but ignores?

[Massimo-B]

I see, --help mentions the defaults, so just add to the man-page for completeness.

Would you like to open a PR with what you want the man page with those examples look like filled in?
