Fix some doc/misc cross-references to separate manuals.
Tweak some over/underfull lines

* doc/misc/ada-mode.texi (Project file variables):
Reword to reduce underfull hbox.
(No project files, Use GNAT project file):
Use smallexample to make some overfull lines less terrible.
* doc/misc/auth.texi (Help for users): Break long lines.
* doc/misc/bovine.texi (Optional Lambda Expression): Allow line break.
doc/misc/wisent.texi tweaks

Improve handling of subprocess shutdown on MS-Windows.

 src/w32proc.c (reader_thread): Do not index fd_info[] with negative
 values.
 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
 after WaitForSingleObject returns normally.  This expedites reader
 thread shutdown when delete_child triggers it.
 (reap_subprocess): More accurate commentary for why we call
 delete_child only when cp->fd is negative.
 src/w32.c (sys_close): Do not call delete_child on a subprocess
 whose handle is not yet closed.  Instead, set its file descriptor
 to a negative value, so that reap_subprocess will call
 delete_child on that subprocess when its SIGCHLD arrives.  This
 avoids closing handles used for communications between sys_select
 and reader_thread, which doesn't give sys_select a chance to
 notice that the process exited and invoke the SIGCHLD handler for
 it.

Don't fail in acl_set_file on MS-Windows if the operation is a no-op.

 src/w32.c (acl_set_file): If setting the file security descriptor
 fails, and the new DACL is identical to the existing one, silently
 return success.  This fixes problems for users backing up their
 own files without having the necessary privileges for setting
 security descriptors.
