Text mode turns off the features concerned with comments except when
you explicitly invoke them. It changes the syntax table so that
single-quotes are considered part of words (e.g., @samp{don't} is
considered one word). However, if a word starts with a single-quote,
apostrophes are considered part of words (e.g., @samp{don't} is
considered one word). However, if a word starts with an apostrophe,
it is treated as a prefix for the purposes of capitalization
(e.g., @kbd{M-c} converts @samp{'hello'} into @samp{'Hello'}, as
