Statements should be indented consistently: allow difference for main blocks

[stefandrissen]

We have quite some conditional compilation as follows:

function foo returns logical (
):
   return true.
end function.

&if somecondition &then

   function bar returns logical (
   ):
      return true.
   end function.

&else

   function nobar returns int64 (
   ):
      return 0.
   end function.

&endif

These are being flagged by the consistent indent rule. Could this rule be fine tuned to allow discrepancies on main block statements such as:

• function
• procedure
• method

method is less of an issue since they are normally all indented, allowing room for an outdented preprocessor. I did however have one case where I thought it made no sense indenting everything except for the class / end class statements so thought it would be useful to put the method statements at the beginning of the line.

It could be possible to exclude a list of statements. There are really so many indentation styles when working with the preprocessor !

@gquerret I agree , e.g. we try to indent ABL independent from &preprocessor

&if {&condition1}
&then

    &if {&condition2}
    &then
procedure A:
end procedure.
    &else
procedure A:
end procedure.
    &endif

&endif

It's more readable when looking at preprocessed code, but it's hard to maintain if a lot of preprocessor conditions are involved.
