//Some of this macro code was originally written with the help of a slickedit
//employee back in the days of visual slick edit for windows (i.e. versions 1-3
//or so). I don't recall who it was. This macro was written before slickedit
//reformatted comments as I typed them and I still use it when I re-indent code.
//The purpose of this macro is to reflow a comment at a new indentation level or
//to just reformat the comment per the document width of 80 using a tab indent
//setting of 4.
//To use this macro you select the comment using line mode making sure your
//cursor is at the new indentation location. Then execute the macro. The comment
//will be reformatted to the new width with the C/C++ "/*" " *" and "*/" to
//open/close the comment.
//Some improvements would be to obtain the document width and tab indent
//settings programatically. In addition, the comment style could be obtained and
//used (this is fixed for the old C style comment format).
