cygpath automatically adds the root-local prefix \\?\ automatically
for paths exceeding 260 bytes. However, it does not add the root-local
prefix if the path contains path components invalid in DOS paths, for
instance path components with trailing dots or spaces.
Add the -r option to always add the root-local prefix to the path.
Add the option to the documentation and improve the help text.

Windows only allows to set the primary group to a group already
present in the TOKEN_GROUP list. Cygwin OTOH fakes success at
setgid() time, to allow a subsequent call to setuid() to do
the actual account switching. To have a sane behaviour in the
command line tool, check group membership and disallow to switch
to groups other than those already present in the user token.

A process which is exiting due to a core dumping signal doesn't
propagate the correct exist status after dumping core, because 'dumper'
itself forcibly terminates the process.
Use 'dumper -n' to avoid killing the dumped process, so we continue to
the end of signal_exit(), to exit with the 128+signal exit status.
Busy-wait in exec_prepared_command() in an attempt to reliably notice
the dumper attaching, so we don't get stuck there.
Also: document these important facts for custom uses of error_start.
Unfortunately fgrep is now deprecated in a very pushy way.
Make sure to use grep -F instead all around, even in docs
and comments/

Pre-format a command to be executed on a fatal error to run 'dumper'
(using an absolute path).
Factor out executing a pre-formatted command, so we can use that for
invoking the JIT debugger in try_to_debug() (if error_start is present
in the CYGWIN env var) and to invoke dumper when a fatal error occurs.
On a fatal error, if the core file size limit is greater than 1MB,
invoke dumper to write a core dump. Otherwise, if that limit is greater
than 0, write a .stackdump file, as previously.
Adjust and clarify the associated documentation.
Also: Fix so that the error_start JIT debugger is now invoked, even when
ulimit -c is zero.
Also: Fix uses of console_printf() inside exec_prepared_command(). It's
output is written via the Windows console device, so needs to use
Windows-style line endings.
Also: consistently return non-zero from try_to_debug() if we debugged.
Future work: Truncate or remove the file written, if it exceeds the
maximum size set by the ulimit.
Future work: Using the words "fatal error" could probably be improved
on. This means exiting on one of the "certain signals whose default
action is to cause the process to terminate and produce a core dump
file".
This function closes or sets the close-on-exec flag for a specified
range of file descriptors. It is available on FreeBSD and Linux.

A more sophisticated (and modern) test harness would probably be useful,
but switching to Automake's built-in test harness gets us parallel test
execution, colourization of failures, simplifies matters, seems adequate
for the current testuite, and means we don't need to write any icky Tcl.
