" This version is a major rewrite by Zvezdan Petkovic.
"
" - introduced highlighting of doctests
" - updated keywords, built-ins, and exceptions
" - corrected regular expressions for
"
" * functions
" * decorators
" * strings
" * escapes
" * numbers
" * space error
"
" - corrected synchronization
" - more highlighting is ON by default, except
" - space error highlighting is OFF by default
"
" Optional highlighting can be controlled using these variables.

" Keep Python keywords in alphabetical order inside groups for easy
" comparison with the table in the 'Python Language Reference'
" https://docs.python.org/2/reference/lexical_analysis.html#keywords,
" https://docs.python.org/3/reference/lexical_analysis.html#keywords.
" Groups are in the order presented in NAMING CONVENTIONS in syntax.txt.
" Exceptions come last at the end of each group (class and def below).
"
" Keywords 'with' and 'as' are new in Python 2.6
" (use 'from __future__ import with_statement' in Python 2.5).
"
" Some compromises had to be made to support both Python 3 and 2.
" We include Python 3 features, but when a definition is duplicated,
" the last definition takes precedence.
"
" - 'False', 'None', and 'True' are keywords in Python 3 but they are
" built-ins in 2 and will be highlighted as built-ins below.
" - 'exec' is a built-in in Python 3 and will be highlighted as
" built-in below.
" - 'nonlocal' is a keyword in Python 3 and will be highlighted.
" - 'print' is a built-in in Python 3 and will be highlighted as
" built-in below (use 'from __future__ import print_function' in 2)
" - async and await were added in Python 3.5 and are soft keywords.

" The word boundaries are *not* the floating-point number boundaries

" highlighted, and invalid number literals are not. For example,

" - a decimal point in '4.' at the end of a line is highlighted,
" - a second dot in 1.0.0 is not highlighted,
" - 08 is not highlighted,
