Weird mangling of a commit log entry in gitweb summary

My recent commit 5e692dcacabd5dbc8ccfb9e37a2d26a574b6dea6
looks like this in "git log":

    Remove postmaster.c's reset_shared() wrapper function.

In gitweb, it shows that way too if you drill down to the
individual commit, but in the summary

https://git.postgresql.org/gitweb/?p=postgresql.git;a=summary

it looks like

6 hours ago     Tom Lane    Remove postc's reset_shared() wrapper function.     commit | commitdiff | tree

What's up with that?

            regards, tom lane
