[ANN] PySourceColor 1.9.6 much new code please review

[mefjr75 at hotmail.com]

Hello all ,
I have just finished PySourceColor.py ver 1.9.6.
I am near the end of this tool, and would appreciate a little bit of
review.
Please help me find the pesky little bugs that have escaped me.
I had much difficulty getting linenumbers to work properly.
If you see a simpler way to do linenumbers, by all means, please share.

Here is the module docstring to start you off:

# PySourceColor.py
#############################################################################
# A python source to colorized html/css/xhtml converter.
# Hacked by M.E.Farmer Jr. 2004
# Python license
#############################################################################
# Now supports two types of output markup:
# - HTML markup does not create w3c valid html, but it works on every
#   browser i've tried so far.
#   (I.E.,Mozilla/Firefox,Opera,Konqueror,wxHTML).
# - CSS markup is w3c validated html 4.01 strict,
#   but will not render correctly on all browsers.
# - XHTML markup is w3c validated xhtml 1.0 strict,
#   like html 4.01, will not render correctly on all browsers.
#############################################################################
# Features:
# -Three types of markup:
#    html (default)
#    css/html 4.01 strict
#    xhtml 1.0 strict
#
# -Can tokenize and colorize:
#    12 types of strings
#    2 comment types
#    numbers
#    operators
#    brackets
#    math operators
#    class / name
#    def / name
#    decorator / name
#    keywords
#    arguments class/def/decorator
#    text
#    linenumbers
#
# -Eight colorschemes built-in:
#    null
#    mono
#    dark (default)
#    dark2
#    lite
#    idle
#    viewcvs
#    pythonwin
#
# -Header and footer
#    set to '' for builtin header / footer
#    or give path to a file containing the html
#    you want added as header and footer
#
# -Linenumbers
#    Supports all styles. New token is called LINE.
#    Defaults to NAME if not defined
#
# Style options
# -ALL markups support these text styles:
#         b = bold
#         i = italic
#         u = underline
# -CSS and XHTML has limited support  for borders:
#     HTML markup functions will ignore these.
#     Optional: Border color in RGB hex
#     Defaults to the text forecolor.
#         #rrggbb = border color
#     Optional: specify one type only
#         - = dashed
#         . = dotted
#         s = solid
#         d = double
#         g = groove
#         r = ridge
#         n = inset
#         o = outset
#     You can specify multiple sides,
#     they will all use the same style.
#     Optional: Default is full border.
#         v = bottom
#         < = left
#         > = right
#         ^ = top
#     NOTE: Specify the styles you want.
#           The markups will ignore unsupported styles
#           Also note not all browsers can show these options
#
# -All tokens default to NAME if not defined
#     so the only absolutely critical ones to define are:
#     NAME, ERRORTOKEN, PAGEBACKGROUND
#

More details in the code.
And for all the commandline junkies there is a commandline interface
that covers every option.
