`zk-id-regexp` does not specify that the regexp should be wrapped in `\\(...\\)`, but some code that matches against the regexp refers to match-string 1 while other instances (e.g. `zk--id-at-point`) do not. Since `zk-link-regexp` and `zk-file-name-regexp` add their own explicitly-numbered capture groups, it's best to consistently refer to the entire match when matching against `zk-id-regexp`.
Removing `\\(...\\)` is not strictly needed, but since both `zk-link-regexp` and `zk-file-name-regexp` add capture groups themselves, it results in a cleaner regexp.

I ran into this accidentally when testing some different values for
zk-id-regexp, which made zk-index completely inoperable, since button actions were not finding the note ID.The docstring does not specify that the regexp should be wrapped in
\\(...\\), but some code that matches against the regexp refers to match-string 1 while other instances (e.g.zk--id-at-point) reference the entire match (i.e. match-string 0). Sincezk-link-regexpandzk-file-name-regexpadd their own explicitly-numbered capture groups, it's best to consistently refer to the entire match when matching againstzk-id-regexp.NB: This pull request would need to be applied before pull request #68, but otherwise there shouldn't be any conflicts.
