* Add missing space for `String#start_with?`.
* Add missing pluses for `String#tr` and
`Methods for Converting to New String` label.
* Move quote into the tag for `Whitespace in Strings` label.
Adds to doc for String.new, also making it compliant with documentation_guide.rdoc.
Fixes some broken links in io.c (that I failed to correct yesterday).
Treats:
#chars
#codepoints
#each_char
#each_codepoint
#each_grapheme_cluster
#grapheme_clusters
Also, corrects a passage in #unicode_normalize that mentioned module UnicodeNormalize, whose doc (:nodoc:, actually) says not to mention it.
As @peterzhu2118 and @duerst have pointed out, putting string method's RDoc into doc/ (which allows non-ASCII in examples) makes the "click to toggle source" feature not work for that method.
This PR moves the primary method doc back into string.c, then includes RDoc from doc/string/*.rdoc, and also removes doc/string.rdoc.
The affected methods are:
::new
#bytes
#each_byte
#each_line
#split
The call-seq is in string.c because it works there; it did not work when the call-seq is in doc/string/*.rdoc.
This PR also updates the relevant guidance in doc/documentation_guide.rdoc.
