Formats a DOI and checks for DOI errors.
DOI names contain two parts: prefix and suffix separated by a forward slash.
Prefix: directory indicator '10.' followed by a registrant code
Suffix: character string of any length chosen by the registrant
This function checks a DOI name for: prefix/suffix. If the DOI name contains spaces or endashes, or, if it ends
with a period or a comma, this function will emit a bad_doi error message.
DOI names are case-insensitive and can incorporate any printable Unicode characters so the test for spaces, endash,
and terminal punctuation may not be technically correct but it appears, that in practice these characters are rarely
if ever used in DOI names.

Formats an HDL with minor error checking.
HDL names contain two parts: prefix and suffix separated by a forward slash.
Prefix: character string using any character in the UCS-2 character set except '/'
Suffix: character string of any length using any character in the UCS-2 character set chosen by the registrant
This function checks a HDL name for: prefix/suffix. If the HDL name contains spaces, endashes, or, if it ends
with a period or a comma, this function will emit a bad_hdl error message.
HDL names are case-insensitive and can incorporate any printable Unicode characters so the test for endashes and
terminal punctuation may not be technically correct but it appears, that in practice these characters are rarely
if ever used in HDLs.
Query string parameters are named here: https://www.handle.net/proxy_servlet.html. query strings are not displayed
but since '?' is an allowed character in an HDL, '?' followed by one of the query parameters is the only way we
have to detect the query string so that it isn't URL-encoded with the rest of the identifier.

Validate and format an ISSN. This code fixes the case where an editor has included an ISSN in the citation but
has separated the two groups of four digits with a space. When that condition occurred, the resulting link looked
like this:
|issn=0819 4327 gives: [https://www.worldcat.org/issn/0819 4327 0819 4327] -- can't have spaces in an external link
This code now prevents that by inserting a hyphen at the ISSN midpoint. It also validates the ISSN for length
and makes sure that the checkdigit agrees with the calculated value. Incorrect length (8 digits), characters
other than 0-9 and X, or checkdigit / calculated value mismatch will all cause a check ISSN error message. The
ISSN is always displayed with a hyphen, even if the ISSN was given as a single group of 8 digits.

Format a PMC, do simple error checking, and check for embargoed articles.
The embargo parameter takes a date for a value. If the embargo date is in the future the PMC identifier will not
be linked to the article. If the embargo date is today or in the past, or if it is empty or omitted, then the
PMC identifier is linked to the article through the link at cfg.id_handlers['PMC'].prefix.
PMC embargo date testing is done in function is_embargoed () which is called earlier because when the citation

returns the embargo date if the PMC article is still embargoed, otherwise it returns an empty string.
