This function does not work if it is fed month names for languages other than English. Wikimedia #time: parser apparently doesn't understand

contains a non-English month name because good1 is false after the call to lang.formatDate(). To get around that
call this function with YYYY-MM-DD format dates.
 
For the time being, to use this function, supply it with YYYY-MM-DD format dates. See

this is the list of patterns for date formats that this module recognizes. Approximately the first half of these
patterns represent formats that might be reformatted into another format. Those that might be reformatted have
'indicator' letters that identify the content of the matching capture: 'd' (day), 'm' (month), 'a' (anchor year),
'y' (year); second day, month, year have a '2' suffix.
 
These patterns are used for both date validation and for reformatting. This table should not be moved to ~/Configuration
because changes to this table require changes to check_date() and to reformatter() and reformat_date()

reformat 'date' into new format specified by format_param if pattern_idx (the current format of 'date') can be
These table are used exclusively for reformatting dates
reformatted. Does the grunt work for reformat_dates().
 
The table re_formats maps patern_idx (current format) and format_param (desired format) to a table that holds:
format string used by string.format()
identifier letters ('d', 'm', 'y', 'd2', 'm2', 'y2') that serve as indexes into a table t{} that holds captures
from mw.ustring.match() for the various date parts specified by patterns[pattern_idx][1]
 
Items in patterns{} have the general form:
['ymd'] = {'^(%d%d%d%d)%-(%d%d)%-(%d%d)$', 'y', 'm', 'd'}, where:
['ymd'] is pattern_idx
patterns['ymd'][1] is the match pattern with captures for mw.ustring.match()
patterns['ymd'][2] is an indicator letter identifying the content of the first capture
patterns['ymd'][3] ... the second capture etc
 
when a pattern matches a date, the captures are loaded into table t{} in capture order using the idemtifier
characters as indexes into t{} For the above, a ymd date is in t{} as:
t.y = first capture (year), t.m = second capture (month), t.d = third capture (day)
 
To reformat, this function is called with the pattern_idx that matches the current format of the date and with
format_param set to the desired format. This function loads table t{} as described and then calls string.format()
with the format string specified by re_format[pattern_idx][format_param][1] using values taken from t{} according
to the capture identifier letters specified by patterns[pattern_idx][format_param][n] where n is 2..

extracts year, month and day from MDY formatted date, places them in the source_date table, and returns.
 
format is one of several manual keywords: dmy, dmy-all, mdy, mdy-all, ymd, ymd-all. The -all version includes
access- and archive-dates; otherwise these dates are not reformatted.
 
This function allows automatic date formatting. In ~/Configuration, the article source is searched for one of
the {{use xxx dates}} templates. If found, xxx becomes the global date format as xxx-all. If |cs1-dates= in
{{use xxx dates}} has legitimate value then that value determines how cs1|2 dates will be rendered. Legitimate
values for |cs1-dates= are:
l - all dates are rendered with long month names
ls - publication dates use long month names; access-/archive-dates use abbreviated month names
ly - publication dates use long month names; access-/archive-dates rendered in ymd format
s - all dates are rendered with abbreviated (short) month names
sy - publication dates use abbreviated month names; access-/archive-dates rendered in ymd format
y - all dates are rendered in ymd format
 
the format argument for automatic date formatting will be the format specified by {{use xxx dates}} with the
value supplied by |cs1-dates so one of: xxx-l, xxx-ls, xxx-ly, xxx-s, xxx-sy, xxx-y, or simply xxx (|cs1-dates=
empty, omitted, or invalid) where xxx shall be either of dmy or mdy.
 
dates are extracted from date_parameters_list, reformatted (if appropriate), and then written back into the
list in the new format. Dates in date_parameters_list are presumed here to be valid (no errors). This function
returns true when a date has been reformatted, false else. Actual reformatting is done by reformatter().
