To keep it in the style of names like esc_param (escaping the GET parameter
to be passed), esc_url (escaping URL to be put as argument of href attribute
of <link> or <a> element) and esc_html (escaping output). 

esc_attr is to escape ATTRibutes of elements, for example title attribute.
I'm not sure if CGI module does escaping for example of '"' in attributes...

Anyone can send patch renaming subroutines. to_utf8 is a good name... till
we allow non-utf8 encodings. And the name can be used for other places where
we do string decoding from Perl internal form to utf-8.

There are two formats used (check out Documentation/SubmittingPatches).

First used for short replies, or some comments which you don't want to have
in commit description (commit message) is to put additional text just right
after "---" separating commit message from the patch.

Second, used for example if reply is longer than commit message, or patch
is just an attachement/footnote to reply, is to put the reply above the
body of message generated by format patch, and separate it from the
patch for example by "-- >8 --". The idea is that committer can remove the
top part of email and apply the rest as is.
