[uf-dev] escaping single values

[brian suda]

In RFC 2426, section 5 (5.  Differences From vCard v2.1, p 36-37)

. Any COMMA or SEMICOLON in a text type value must be backslash escaped.

In the RFC 3.1.1 FN Type Definition, example
  Type value: A single text value.
   Type example:
        FN:Mr. John Q. Public\, Esq.

So FN (which is a single value) is defined as a "Text Value", which must
be escaped by section 5. Then in their example, they also escape the comma.

My vote is that it should stay, and that escaping commas and semicolons
is the correct behavior if it is singular or plural.
