New Textobj: item in list seperated with "," or similar

[gerazov]

Textobj requested

Select item in a list of items separated with , . Although treesitter parsers already do this for code (#58) via the in argument mechanic nvim-treesitter-textobjects, it would be useful to have it for lists in pure text, e.g.

This is a list of items in: rst, md, txt, text, mail files. 

Also could come in handy for comments in code scripts that list stuff.

The syntax would be i<separator> for inner and a<separator> for outer. Here <separator> can be ,, ;, ...

Inner/Outer Difference

In it's simplest use-case - inner i, would not take the separator, and around a, would e.g. if your cursor is on text then:

This is a list of items in: rst, md, txt, text, mail files. 
                                          |--| inner
                                outer   |----|

Edge cases would be the first element:

• the right bound is the ,
• the left bound:
  • if there is a : or - starting the list than it is taken as a bound of the first item,
  • if not then the first item could be a single word.

And for the last element:

• the right bound is the .
• the left bound:
  • the and if there is one
  • the previous ,

Checklist

• The textobj would be useful to more users than just me.
• There is no lua plugin already implementing the textobj in an adequate manner.
• I read the docs and there is no such textobj already.
