Usage documentation for string_algo split does not work as advertised

[Steven Sims <steven.sims@…>]

Sorry that this is so trivial, but it has been around for years...

In doc/html/string_algo/usage.html#id1761650

string str1("hello abc-*-ABC-*-aBc goodbye");

[snip]

split( SplitVec, str1, is_any_of("-*") ); SplitVec == { "hello abc","ABC","aBc goodbye" }

No it isn't; the result includes empty strings because of the grouped separators in "-*-". To produce the 3 strings as in the comment needs:

split( SplitVec, str1, is_any_of("-*"), token_compress_on );
