[PATCH] run-command documentation: add 4 missing slashes

[Miklos Vajna <vmiklos@frugalware.org>]

When initializing the struct async and struct child_process structures,
the documentation suggested "clearing" the structure with '0' instead of
'\0'.

Also asciidoc would parse '\0' as a markup, changing it to \'0' prevents
this.
