It was impossible to view systemd.nspawn(5), because systemd-nspawn(1) was matched
also, and happened to be earlier in the list. The solution in this patch is pretty
crude, but is should be enough for our purposes, since we don't have any regexp
special characters in man page names except for the dot.
Man page generation is generally very slow. I prefer to use -Dman=false when
developing systemd, and only build specific pages when introducing changes.
Those two little helper tools make it easy:
$ build/man/man systemd.link
$ build/man/html systemd.link
will show systemd.link.8 and systemd.link.html from the build directory build/.
