mfc71.dll was only needed for Python2.4
msvc*.dll is similarly optional

'''colorize output from some commands
This extension modifies the status command to add color to its output
to reflect file status, the qseries command to add color to reflect
patch status (applied, unapplied, missing), and to diff-related
commands to highlight additions, removals, diff headers, and trailing
whitespace.
Other effects in addition to color, like bold and underlined text, are
also available. Effects are rendered with the ECMA-48 SGR control
function (aka ANSI escape codes). This module also provides the
render_text function, which can be used to add effects to any text.
Default effects may be overridden from the .hgrc file:
[color]
status.modified = blue bold underline red_background
status.added = green bold
status.removed = red bold blue_background
status.deleted = cyan bold underline
status.unknown = magenta bold underline
status.ignored = black bold
# 'none' turns off all effects
status.clean = none
status.copied = none
qseries.applied = blue bold underline
qseries.unapplied = black bold
qseries.missing = red bold
diff.diffline = bold
diff.extended = cyan bold
diff.file_a = red bold
diff.file_b = green bold
diff.hunk = magenta
diff.deleted = red
diff.inserted = green
diff.changed = white
diff.trailingwhitespace = bold red_background
