[elpa] externals/vertico 5e5192f 2/6: Improve prompt selection

[Protesilaos Stavrou]

branch: externals/vertico
commit 5e5192fbcbee314e056f2db356aedd9f6187db0c
Author: Daniel Mendler <mail@daniel-mendler.de>
Commit: Daniel Mendler <mail@daniel-mendler.de>

    Improve prompt selection
    
    Do not select the prompt if the first candidate equals the input after the
    completion boundary. This avoids jumping between candidate and prompt. A
    candidate matching the input after the completion boundary will always be 
moved
    first. This is a refinement of the previous commit, see #4. It is getting a 
bit
    complicated unfortunately. Thank you for talking me into this, @oantolin...
