Maybe, maybe not. It depends on the driver, and on what the parent
tries to do. If the parent does nothing but call POSIX:_exit, then
it probably won't be affected.

This FAQ could do with mentioning Win32::Console::ANSI, to get ANSI
color escapes on Win32. Maybe something like
On Win32, the native console doesn't understand ANSI escapes, but
you can use the Win32::Console::ANSI module to translate ANSI
sequences into something it can understand. If you want your code to
be portable to Win32 systems, you will need to include
BEGIN {
if ($^O eq "MSWin32" and -t STDOUT) {
require Win32::Console::ANSI;
}
}
or
use if $^O eq "MSWin32" && -t STDOUT, "Win32::Console::ANSI";
before C<use Term::ANSIColor;>.

I found this example, which you may recognize, they start off with data,
notice the indentation:
Skipper
blue_shirt
hat
Professor
sunscreen
water_bottle
Gilligan
red_shirt
hat
Then, as they read the lines of data, they want to determine if the data is
the person's name, or an item belonging to that person. They use the
following:
if (/^(\S.*)/) {...
This will determine whether or not there is a non-white space (person name)
at the begining of the line. Would the following achieve the same, in this
case? If so, is there an advantage to their pattern?
if (/^\S/) {...

... and additionally saves the line (minus newline) into the $1 variable.

That depends on whether the $1 variable is subsequently used or not.

You have not shown enough of "this case" to be able to answer your question.
> If so, is there an advantage to their pattern?
It saves the line (minus newline) into the $1 variable.
That would be an advantage if the code later makes use of
the $1 variable's value.
> if (/^\S/) {...
That does not put anything into the $1 variable.

For the part of the code you showed to us: yes

It also captures the whole name if there is a name

That's true if F<syntax/perl.vim> is off vim-scripts.sf.net. However
for F<perl.vim> distributed with Debian's Lenny (and I suppose that
ubuntu thing too), that 'ordinary code' is a way limited. OP seems to
be from Mac world, so I can't comment what would be 'ordinary code' for
his ordinary perl.vim.

The hash sign isn't the cause of the problem there. Replace it with
anything else, and you'll still see the same error.

And even that is not true (and many existing syntax highlighters get this
wrong as well):
while (<>) {
/^#/ and next;
...
}

Why not capture something when you already know what it is?
Why not a single letter in the sequence.
Maybe $-[1] is something you need to know. Maybe you want to
rip out or assign substr style.
Been at this very long?

We've generated our own small collection of expressions which tell us
what is and is not a legal file name in uSWindows and UNIX. But we
were wondering, has anyone published a collection of expressions to
that purpose - validating file names?

Do you tell them to go back to college? lose weight?
As OP, I certainly didn't ask about the dumb sidebar issue of File::Slurp.

I said that Sean Hannity took residence up Newt Gingrich's butt from 94 to
98. I got that from British intelligence. It turns out he only took up
residence in 95.
