This is mostly a bug-fix release. However, some functionality has been added.
	
	+ added functions which can handle dstrings with embedded binary zeros
	(their names has `_bin' suffix)

	* `ds_fromdouble' now handles zero precision properly
	* `skip_spaces' now work exactly as `skip_spaces_nc' if `util_comment_character' 
	is set to null
	* `imap_file' works better when emulating mapping


Version 1.0.2
This is a bug-fix release
	* some routines handle NULL args better
	* a bit cleaner dstring garbage collection
	* a better way to convert from numbers to dstrings
	* a faster dstring storage expansion

Version 1.0.1

This is mostly a bug-fix release.
User-visible changes include:
	+ now all dstring-related functions treat NULL as an empty string
	- stack routines are excluded since they were not actually used
	* using `skip_ifs' doesn't cause line miscount
	* checking chunk size doesn't cause bus error on strong-alignment archs
	* various cleanups in headers and auxiliary files
