Sv: New startup options, show<n>levels

["Gustav Wikström" <gustav@whil.se>]

Hi,

I believe we still can change the name if that’s preferred. I'm not overly attached to the name I committed, although I fail to see the ugliness in it. And it's only in master since a few days. No biggie to change.

In my opinion it's important to see the names in their context. One context is the other available startup options.

Principles I tried to follow when choosing the names (Alt 0 below):
1) Keep the name as close to the intent as possible. It should be possible to understand it based on name alone, if possible. (I.e. avoid ambiguity)
2) Let the pattern for the name match with the pattern already existing for names in its surrounding context.
3) Keep it short, but prefer principle 1 and 2 to short.

The following options have been presented, where the first one is already in master:

Already in master (Alt 0): 
 `overview'        Top-level headlines only.  
 `content'         All headlines.             
 `show2levels'     Headline levels 1-2.       
 `show3levels'     Headline levels 1-3.       
 `show4levels'     Headline levels 1-4.       
 `show5levels'     Headline levels 1-5.       
 `showall'         No folding on any entry.   
 `showeverything'  Show even drawer contents. 

Alt 1:
 `overview'        Top-level headlines only.  
 `content'         All headlines.             
 `show:2'          Headline levels 1-2.       
 `show:3'          Headline levels 1-3.       
 `show:4'          Headline levels 1-4.       
 `show:5'          Headline levels 1-5.       
 `showall'         No folding on any entry.   
 `showeverything'  Show even drawer contents. 

Alt 2:
 `overview'        Top-level headlines only.  
 `content'         All headlines.             
 `levels:2'        Headline levels 1-2.       
 `levels:3'        Headline levels 1-3.       
 `levels:4'        Headline levels 1-4.       
 `levels:5'        Headline levels 1-5.       
 `showall'         No folding on any entry.   
 `showeverything'  Show even drawer contents. 

Alt 3:
 `overview'        Top-level headlines only.  
 `content'         All headlines.             
 `content:2'       Headline levels 1-2.       
 `content:3'       Headline levels 1-3.       
 `content:4'       Headline levels 1-4.       
 `content:5'       Headline levels 1-5.       
 `showall'         No folding on any entry.   
 `showeverything'  Show even drawer contents.

To me no option is perfect. There are incongruencies for all. Maybe a fourth option?

Alt 4:
`overview'        Top-level headlines only.  
 `content'         All headlines.             
 `2levels'         Headline levels 1-2.       
 `3levels'         Headline levels 1-3.       
 `4levels'         Headline levels 1-4.       
 `5levels'         Headline levels 1-5.       
 `showall'         No folding on any entry.   
 `showeverything'  Show even drawer contents.

Since show in showall and showeverything seems to symbolize the unfolding of things.

That would be an improvement based on all three principles above, in that it removes the ambiguity of "show" (and how it relates to unfolding), makes the names shorter, and stays in line with the naming convention (i.e. no ':'). Not sure what the syntax says about names starting with numerals though.

Your call. Personally I'd prefer Alt 4 or the existing one.
