/**
* General indenting approach:
* Indenting levels are put into a stack.
*
* The stack entries contain:
* - opening type
* - brace column
* - continuation column
*
* Items that start a new stack item:
* - preprocessor (new parse frame)
* - Brace Open (Virtual brace also)
* - Paren, Square, Angle open
* - Assignments
* - C++ '<<' operator (ie, cout << "blah")
* - case
* - class colon
* - return
* - types
* - any other continued statement
*
* Note that the column of items marked 'PCF_WAS_ALIGNED' is not changed.
*
* For an open brace:
* - indent increases by indent_columns
* - if part of if/else/do/while/switch/etc, an extra indent may be applied
* - if in a paren, then cont-col is set to column + 1, ie "({ some code })"
*
* Open paren/square/angle:
* cont-col is set to the column of the item after the open paren, unless
* followed by a newline, then it is set to (brace-col + indent_columns).
* Examples:
* a_really_long_function_name(
* param1, param2);
* a_really_long_function_name(param1,
* param2);
*
* Assignments:
* Assignments are continued aligned with the first item after the assignment,
* unless the assign is followed by a newline.
* Examples:
* some.variable = asdf + asdf +
* asdf;
* some.variable =
* asdf + asdf + asdf;
*
* C++ << operator:
* Handled the same as assignment.
* Examples:
* cout << "this is test number: "
* << test_number;
*
* case:
* Started with case or default.
* Terminated with close brace at level or another case or default.
* Special indenting according to various rules.
* - indent of case label
* - indent of case body
* - how to handle optional braces
* Examples:
* {
* case x: {
* a++;
* break;
* }
* case y:
* b--;
* break;
* default:
* c++;
* break;
* }
*
* Class colon:
* Indent continuation by indent_columns:
* class my_class :
* baseclass1,
* baseclass2
* {
*
* Return: same as assignments
* If the return statement is not fully paren'd, then the indent continues at
* the column of the item after the return. If it is paren'd, then the paren
* rules apply.
* return somevalue +
* othervalue;
*
* Type: pretty much the same as assignments
* Examples:
* int foo,
* bar,
* baz;
*
* Any other continued item:
* There shouldn't be anything not covered by the above cases, but any other
* continued item is indented by indent_columns:
* Example:
* somereallycrazylongname.with[lotsoflongstuff].
* thatreallyannoysme.whenIhavetomaintain[thecode] = 3;

/**
* REVISIT: This needs to be re-checked, maybe cleaned up
*
* Indents comments in a (hopefully) smart manner.
*
* There are two type of comments that get indented:
* - stand alone (ie, no tokens on the line before the comment)
* - trailing comments (last token on the line apart from a linefeed)
* + note that a stand-alone comment is a special case of a trailing
*
* The stand alone comments will get indented in one of three ways:
* - column 1:
* + There is an empty line before the comment AND the indent level is 0
* + The comment was originally in column 1
*
* - Same column as trailing comment on previous line (ie, aligned)
* + if originally within TBD (3) columns of the previous comment
*
* - syntax indent level
* + doesn't fit in the previous categories
*
* Options modify this behavior:
* - keep original column (don't move the comment, if possible)
* - keep relative column (move out the same amount as first item on line)
* - fix trailing comment in column TBD
*
* @param pc The comment, which is the first item on a line
* @param col The column if this is to be put at indent level
