Make sure this is documented. Wait, I demonstrated that it could be
done on two lines.

I don't want lines to wrap etc. on my terminal or printer. Call me old

rms> # compile-command: "invoke-rc.d chrony restart && sleep 2`\
rms> #` && grep chrony /var/log/syslog|tail -19"

Indeed that works, no need for /bin/sh's ":", and one can even remove
the backslash.  One can go on and on:

# Local Variables:
# compile-command: "p=$PWD && cd /tmp && procmail -m LOGABSTRACT=all `
#` VERBOSE=on $p/.procmailrc.local.post </dev/null `
#` bla bla"
# End:

OK, remember to document this `#` hack.  As this always is sent to sh,
this should always work.  And document simpler ways for those who
don't need to hide local variables in comments, e.g.,

rms> # compile-command: "invoke-rc.d chrony restart && sleep 2 \
rms> && grep chrony /var/log/syslog|tail -19"

By the way, the documentation, both of local variables and compile,
could also say compile-command is a great local variable to set.
E.g., my .crontab file has

# Local Variables:
# compile-command: "crontab .crontab"
# End:
