" XXX - breaks if close attempted while XIM is in preedit mode
" TODO - allow usability as a global plugin -
"    Add g:unaryTagsStack - always contains html tags settings
"    and g:closetag_default_xml - user should define this to default to xml
"    When a close is attempted but b:unaryTagsStack undefined,
"    use b:closetag_html_style to determine if the file is to be treated
"    as html or xml.  Failing that, check the filetype for xml or html.
"    Finally, default to g:closetag_html_style.
"    If the file is html, let b:unaryTagsStack=g:unaryTagsStack
"    otherwise, let b:unaryTagsStack=""
" TODO - make matching work for all comments
"  -- kinda works now, but needs syn sync minlines to be very long
"  -- Only check whether in syntax in the beginning, then store comment tags
"  in the tagstacks to determine whether to move into or out of comment mode
" TODO - The new normal mode mapping clears recent messages with its <ESC>, and
" it doesn't fix the null-undo issue for vim 5.7 anyway.
" TODO - make use of the following neat features:
"  -- the ternary ?: operator
"  -- :echomsg and :echoerr
"  -- curly brace expansion for variables and function name definitions?
"  -- check up on map <blah> \FuncName
"
