de108d3fc0 -idle: don't lazy-unmount 
When a process has its working dir inside the mount,
the only way we notice is that we get EBUSY when trying
to unmount.

We used to lazy-unmount in this case, but this means
pulling the rug from under the process.

For example, bash will start throwing

  cd: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory

messages.

are not comparable when the cpu is different.

Also update encfs results.

9178aa1534 MANPAGE: describe how to unmount, and that default options are fine 
Feedback received during the recent Go user group. If you haven't
used FUSE before, you don't know how to unmount, and it was not
described in the man page!

As for the options, there are many, and new users are intimidated
by it. State clearly that defaults are fine.

372e0333b3 Fix 'cannot adjust line' warning from man in gocryptfs manpage. 
When generating man pages, pandoc marks indented code blocks with the
roff macro '.nf'. That avoids a warning from man related to the long
line about the master key.

3bc100aeb3 reverse mode: support wildcard exclude (--exclude-wildcard) 
This adds support for gitignore-like wildcards and exclude patters in
reverse mode. It (somewhat) fixes #273: no regexp support, but the
syntax should be powerful enough to satisfy most needs.

Also, since adding a lot of --exclude options can be tedious, it adds
the --exclude-from option to read patterns from a file (or files).

61940a9c06 Include rendered man page in source tarballs 
This gives users who build from the source tarball, but
do not want to install pandoc, access to the man pages.

Apperently the gocryptfs homebrew package ships without
the man pages at the moment to avoid pandoc.
