"Match next pair" with [/] followed by m (or: a better vi" from VIM)

[ysooqe]

Basic idea: extend [ and ] with the option to goto (select) the next or previous "pair" by using the m key in the [ and ] minor modes.

I have looked around the discussions and issues and found a related one each:
#7847 and the very last comment of #1072

This would basically enable VIMs vi" (or related pairs) functionality, but in a much more powerful way:
All the goodness of the match minor mode combinded with the ability to goto (or select) the next or previous pair by prefixing m with either [ or ].

Examples:
This is a line that contains some (brackets) as well as a second (pair) of brackets.
The caret is on the first character of the line (T).
By pressing ]mim (or ]mi(), "brackets" would be selected. By pressing 2]mim instead, "pair" would be selected.

Note: Since the behaviour of 2]<char> is inconsistent at the moment though (2]p selects the next two paragraphs while 2]f selects only the second function), it could be discussed if 2]mim should select only the second matching pair (behaviour like 2]f) or if it should create two simultaneous selections which would be more in line with with behaviour of 2]p; albeit a little different still since <num>]p is always just one (big) selection and <num>]mim would then be n-multiple selections.
Since <num>]p behaviour seems to be an outlier though compared to the others, I think it would be more consistent though to make <num>]mim select only the second one and if you want to select both then this should be handled by searching for brackets and extending the search with v.
