	* include/ext/vstring.h (__versa_string<>::operator+, all
	versions): Move out of line...
	* include/ext/vstring.tcc (__versa_string<>::operator+): ...
	here; consistently use reserve for the benefit of sso_string_base;
	prefer push_back to single-char append when appropriate.

	* include/ext/vstring.h (__versa_string<>::push_back): Don't
	call _M_reserve, _M_mutate instead.
	(reserve): Just forward to _M_reserve.
	* include/ext/vstring.tcc (__versa_string<>::_M_reserve): Remove.
	* include/ext/rc_string_base.h (__rc_string_base<>::_M_reserve): Also
	do the initial checks (first on length, in case __res == capacity).
	* include/ext/sso_string_base.h (__sso_string_base<>::_M_reserve:
	Likewise; don't call _M_set_length unnecessarily.

2005-12-04  Paolo Carlini  <pcarlini@suse.de>

	* include/ext/vstring.h (__versa_string<>::_M_append): New.
	(append(const __versa_string&), append(const __versa_string&,
	size_type, size_type), append(const _CharT*, size_type),
	append(const _CharT*)): Use it.
	(append(size_type, _CharT)): Delegate to _M_replace_aux.
	(assign(const __versa_string&, size_type, size_type),
	assign(const _CharT*), replace(size_type, size_type,
	const _CharT*, size_type)): Forward to _M_replace.
	* include/ext/vstring.tcc (__versa_string<>::_M_append):
	Define, core append functionality.
	(_M_replace): Simplify, move __s == 0 case to _M_replace_aux.
	(_M_replace_aux): Reorganize, don't call _M_replace.

2005-12-04  Paolo Carlini  <pcarlini@suse.de>

	* include/ext/vstring.tcc (__versa_string<>::_M_replace):
	Perform _M_check_length at the beginning and remove it from ...
	(replace, _M_replace_dispatch, _M_replace_aux, assign): ... here.
	(assign): Now move inline.
	(resize): Don't call _M_check_length redundantly, append does.

	Add non const version.
	* include/ext/rc_string_base.h (__rc_string_base<>::_M_get_allocator):

	* include/ext/vstring.h (__versa_string<>::_M_replace_safe):
	Remove.
	* include/ext/vstring.h (__versa_string<>::_M_replace): New, does
	the in-place work or delegates to _M_mutate in case of reallocation.
	* include/ext/vstring.tcc (__versa_string<>::_M_replace_safe):
	Remove.
	* include/ext/vstring.tcc (__versa_string<>::_M_replace): Define.

	* include/ext/sso_string_base.h (__sso_string_base<>::_M_mutate):
	Change to manage only reallocations.
	* include/ext/rc_string_base.h (__rc_string_base<>::_M_mutate):
	Likewise.

	* include/ext/vstring.h (__versa_string<>::insert(size_type,
	const __versa_string&), insert(size_type, const __versa_string&,
	size_type, size_type), insert(size_type, const _CharT*, size_type),
	insert(size_type, const _CharT*)): Delegate to replace.

	* include/ext/vstring.h (__versa_string<>::reserve): Move out of
	line.
	* include/ext/vstring.tcc (__versa_string<>::reserve): Do the
	checks and call _M_reserve.
	* include/ext/vstring.h (__versa_string<>::append): Call _M_reserve
	instead of reserve.
