[strings] Use "Equivalent to" where appropriate #165
Description
From an email by Jeffrey Yasskin:
Many functions in the strings clause use formulations like:
[string.cons]/15:
Effects: Same as basic_string(il.begin(), il.end(), a).
[string.capacity]/15:
Effects: Behaves as if the function calls:
erase(begin(), end());
[string::insert]/27:
Effects: insert(p, il.begin(), il.end()).
Returns: [what the above insert() call returns]
instead of the "Equivalent to" wording defined in
[structure.specifications]/4. These should all be changed to
"Equivalent to" for consistency and conciseness.
