Support "enclosing <symbol>" transformation

[pokey]

We'd like to support transformations such as "outer round" to take everything inside and including the parentheses containing a token, as well as "inner round", "inner square", etc.

Would also be nice to support selecting the delimiter symbols themselves, eg the open and close paren. This could be eg "border round", "border square", etc. Or "disc", or "doughnut", or "bound" or something. This version of the transformation would be useful when combined with a list-based "replace with" command, so could say eg "replace border round with square" to change enclosing parens to square brackets.

Any thoughts on term for selecting the delimiter symbols themselves? Considering:

• "boundary"
• "bound"
• "border"
• "doughnut"
• "disc"
• "edge"
• "flank"
• "hedge"
• "fringe"

"bound" would be my vote.

Yeah I like "bound" too. Will need to see if it conflicts with "round" in practice

Bound sounds good
