I ment [^\/] of cause.
[a] matches only "a" and [^a] matches all characters except "a".
Thus [^\/] should match all letters which are not "/" preventing problems
with paths which contain 'texutil:

~> perl -e 'my $foo = "/foo/texutil/bar/texutil.pl"; $foo =~ s/texutil.*?$//i; print "$foo\n";'
/foo/
~> perl -e 'my $foo = "/foo/texutil/bar/texutil.pl"; $foo =~ s/texutil[^\/]*$//i; print "$foo\n";'
/foo/texutil/bar/
