* $Log: dolist.c,v $
* Revision 4.0.1.5 92/06/08 13:13:27 lwall
* patch20: g pattern modifer sometimes returned extra values
* patch20: m/$pattern/g didn't work
* patch20: pattern modifiers i and o didn't interact right
* patch20: @ in unpack failed too often
* patch20: Perl now distinguishes overlapped copies from non-overlapped
* patch20: slice on null list in scalar context returned random value
* patch20: splice with negative offset didn't work with $[ = 1
* patch20: fixed some memory leaks in splice
* patch20: scalar keys %array now counts keys for you
*
* Revision 4.0.1.4 91/11/11 16:33:19 lwall
* patch19: added little-endian pack/unpack options
* patch19: sort $subname was busted by changes in 4.018
*
* Revision 4.0.1.3 91/11/05 17:07:02 lwall
* patch11: prepared for ctype implementations that don't define isascii()
* patch11: /$foo/o optimizer could access deallocated data
* patch11: certain optimizations of //g in array context returned too many values
* patch11: regexp with no parens in array context returned wacky $`, $& and $'
* patch11: $' not set right on some //g
* patch11: added some support for 64-bit integers
* patch11: grep of a split lost its values
* patch11: added sort {} LIST
* patch11: multiple reallocations now avoided in 1 .. 100000

* patch4: added global modifier for pattern matches
* patch4: // wouldn't use previous pattern if it started with a null character
* patch4: //o and s///o now optimize themselves fully at runtime
