Turns out what also breaks it is what might be a bug in Bash causing
HIST* vars in Debian's .bashrc trim the history immediately, before wwe
get a chance to set it to a huge number.

The workaround -- which cannot be done safely within bashum -- is to
comment any HIST* variables in your .bashrc.

We already call it that way internally.

On Fedora, commonmark is from nodejs-commonmark, which is long-term
broken.

lrep() and prep() repeat every line, or whole stream, on stdin
$1 times.

People can now run

    __bashum_run_n 100 echo hello world

and it will print "hello world" 100 times, instead of just running
`echo` 100 times and ignoring the `hello world` part.
