Why the 'for' loop?
Also, if you're using the 'for' loop for the $_ side-effect, then why
not the simpler:
It was cargo cult programming, with some Google searching to select

scripts, hence the down select.

A lot better. Will fix.

Although that works, I'm not sure that it's really all that desirable
due to the unnecessary and potentially confusing 'for' loop. I'd
probably just write it as:
unlink $ErrsFile if -f $ErrsFile !-s _;
The lone '_' is magical[1] in that it re-uses the stat() information
from the -f rather than stat'ing $ErrsFile again. I'd also probably
replace !-s (not non-zero size) with -z (zero size):
unlink $ErrsFile if -f $ErrsFile -z _;
And, if you're using Perl 5.10 or later, you could use a little
syntactic sugar[1] and stack the file test operators up against one
another:
unlink $ErrsFile if -f -z $ErrsFile;
which is the equivalent of the above with the sugar removed.

And, if you're using Perl 5.10 or later,
The Msysgit (@1.9.5) uses perl v5.8.8, while the newer G4W SDK uses perl
5, version 20, subversion 2 (v5.20.2), so there is a decision to be made
about whether to leave the Msysgit version behind.
While it would be nice to use the newest version, I'm minded that we
should keep a little backward compatibility with Msysgit, at least until
the new G4w has had a few 'proper' releases, so not use the magic
suggestion below.
I've cc'd dscho, Johannes, J6t and Sebastian in case they have any firm
opinions with respect to the Msysgit / G4W split.
