[Bug-indent] indent documentation bugs

[Chipzz]

Hi!

While reading the indent man page, I found a few mistakes in it:

In the "INDENTATION" paragraph, the -ip option is mentioned twice. The
second mentioning should be -pi instead of -ip.

Also, the man page mentions the existance of a --no-tabs option, which does
not exist (only -nut does).

Finally, the "COMMON STYLES" paragraph mentions the -ndj option for the GNU
style, which is not documented any further (maybe deprecated?)

The same mistakes are also present in the info file (which is pretty
logical, I guess)

Also, the email adress which to report bugs to doesn't seem to work. (It
should be 'address@hidden' where README says it is 'address@hidden')

Kind regards,
