[elpa] master 5e49ddf 08/29: Take the exact candidate as an nonoptional arg

[Dmitry Gutov]

branch: master
commit 5e49ddf3d2fe8baf1eff12383df2c6dc5ead9ef7
Author: Kiso Katsuyuki <address@hidden>
Commit: Kiso Katsuyuki <address@hidden>

    Take the exact candidate as an nonoptional arg
    
    By this change `company-preview-show-at-point`
    takes the exact completion candidate
    as an nonoptional arg. So the candidate was added as
    the arg where this function is called.
    
    At the previous change `company-preview-frontend` was modified to
    take the new argument, but it was returned at this time.
    Made `company-preview-common-frontend` not to call
    `company-preview-frontend`, and instead it called
    `company-preview-show-at-point` directly.
