TRUE and parse_found_group is FALSE when this function is called, an address
which is the start of a group (i.e. preceded by a phrase and a colon) is
recognized; the phrase is ignored and the flag parse_found_group is set. If
-this flag is TRUE at the end of an address, then if an extraneous semicolon is
-found, it is ignored and the flag is cleared. This logic is used only when
-scanning through addresses in headers, either to fulfil the -t option or for
-rewriting or checking header syntax.

+This logic is used only when scanning through addresses in headers, either to
+fulfil the -t option, or for rewriting, or for checking header syntax. Because
+the group "state" has to be remembered between multiple calls of this function,
+the variables parse_{allow,found}_group are global. It is important to ensure
+that they are reset to FALSE at the end of scanning a header's list of
+addresses.
Arguments:
mailbox points to the RFC822 mailbox
charset the name of the character set; NULL => iso-8859-1
buffer the buffer to put the answer in
buffer_size the size of the buffer
+ fold if TRUE, a newline is inserted before the separating space when
+ more than one encoded-word is generated
Returns: pointer to the original string, if no quoting needed, or
pointer to buffer containing the quoted string, or
