o  blockArgumentsOnNewLine
return the blockArgumentsOnNewLine flag; if on, block arguments
are on a new line.
defaults to true in original formatter; false in ST/X

Instance protocol:

accessing
o  codeStream

o  firstLineLength

o  format: aNode

o  isMultiLine

o  lastLineLength

o  rewriteOldAssignments: aBoolean
if true (which is the default), old style assignments '_'
are formatted as ':='.
There is only one use of turning this off: when the original
source is to be preserve (i.e. when generating code for an old ST,
or showing a searchString's original pattern)

o  suppressAfterComment: something

o  suppressBeforeComment: something

additions - ST/X
o  addTab

copying
o  postCopy

initialize-release
o  initialize

private
o  crNoIndent

o  for: aValue do: doBlock separatedBy: separatorBlock
This is implemented here since IBM Smalltalk doesn't implement a do:separatedBy: method

o  indent

o  indent: anInteger while: aBlock

o  indentOnly

o  indentWhile: aBlock

o  lineLength

o  lineStart: aPosition

o  maxLineSize

o  maximumArgumentsPerLine

o  needsParenthesisFor: aNode
if original code had parentheses - generate them again

o  possiblyIndent
cr-tab - but only if not already at beginning

o  precedenceOf: parentSelector greaterThan: childSelector
Put parentheses around things that are preceived to have 'lower' precedence. For example, 'a + b * c'
-> '(a + b) * c' but 'a * b + c' -> 'a * b + c'

o  selectorsToLeaveOnLine

o  selectorsToStartOnNewLine

private-formatting

o  formatArrayNodeExpressions: statements singleLine: singleLine

o  formatLiteral: aLiteralNode
to preserve the original radix...

o  formatLiteralArray: aLiteralNode

o  formatMethodPatternFor: aMethodNode

o  formatPragma: aPragmaNode

o  formatStatementsFor: aSequenceNode
self formatStatementComments:(stat commentsAfter) for:stat.

o  formatSymbol: aSymbol
Format the symbol, if it's not a selector then we must put quotes around it. The and: case below,
handles the VisualWorks problem of not accepting two bars as a symbol.
