* new-features.sgml: Add automounting of /, /usr/bin, and /usr/lib.

Browse Source 
* pathnames.sgml (pathnames-intro): Be more verbose about POSIX and
	Win32 paths.
	(mount-table): Add "auto" flag.  Add a paragraph about /usr/bin and
	/usr/lib.
	(pathnames-mount-ex): Enhance flags output.

- Cygwin creates the mount points for /, /usr/bin, and /usr/lib automatically
from it's own position on the disk. They don't have to be specified in
/etc/fstab.
- If a filename cannot be represented in the current character set,
the character will be converted to a sequence Ctrl-N + UTF-8 representation
of the character. This allows to access all files, even those not

<para>Cygwin supports both Win32- and POSIX-style paths. Directory
delimiters may be either forward slashes or backslashes. Paths using
backslashes are always handled as Win32 paths. POSIX paths must only
use forward slashes as delimiter, otherwise they are treated as Win32
paths and file access might fail in surprising ways. Note that the
usage of Win32 paths, though possible, is deprecated, since it
circumvents important internal path handling mechanisms. UNC pathnames
(starting with two slashes and a network name) are also supported.
