Editor modifications... ('home' key behavior)

[Chet Simpson]

Greetings!

I just started using KDevelop today and have already made a modification :)

Since I didn't find it in the buglist or wishlist, I thought I would post it here for others to
play around with and give opinions.....

The change is applied to KWriteView::home() and changes the behavior to move to the first
non-space character of the line. If the cursor is already at the first non-space character in the
line, it will default to it's original behavior and move to the zero position.

Enjoy!

New code:

void KWriteView::home(VConfig &c) {
  int length;
  int xpos;
  TextLine* currLine;

  currLine = kWriteDoc->textLine(cursor.y);
  length = kWriteDoc->textLength(cursor.y);
  xpos = 0;

  if(0 != length) {
    // Find the first non-space character in the line
    while(xpos < length && isspace(currLine->getChar(xpos))) {
      xpos++;
    }

    // If the entire line is blank or the cursor is already at the first
    // non-space character in the line, go to the zero-position
    if(xpos == length || xpos == cursor.x) {
      xpos = 0;
    }
  }

  // Set the new cursor position
  cursor.x = xpos;
  cOldXPos = cXPos = kWriteDoc->textWidth(cursor);

  update(c);
}
