[Bug 1169160] [NEW] cron: non-canonical MIME charset used in mail

[Malcolm Scott]

Public bug reported:

cron sends mail with the following header:

  Content-Type: text/plain; charset=ANSI_X3.4-1968

This is a non-canonical alias for the preferred charset name "us-ascii"
[1].  A previous changelog entry (for 3.0pl1-101) states that this was
previously fixed:

    - Do not use ANSI_x3.4-1968 but US-ASCII instead since it is the preferred
      MIME name as per http://www.iana.org/assignments/character-sets"
      (Closes: #415302)

However the code to do this translation is not currently working due to
an incorrect assumption about the case of nl_langinfo's output (it
currently returns "ANSI_X3.4-1968", whereas the code checks case-
sensitively for "ANSI_x3.4-1968").
