Subject: over_idx: simplify each_by_mid
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1963b46a8d747cd7dfd372085ef79fff1a5bfd48;p=thirdparty%2Fpublic-inbox.git

over_idx: simplify each_by_mid

Eliminate a useless use of `map {}' and avoid a needless `push'
op since the `join' op can just take extra arg.
