Use backticks instead of single quotes in qm resize description

Single quoted text in asciidoc is rendered in man pages
with underlines, which makes the '+' symbol very similar to '+/-'

Backticks are rendered with monospace text in HTML, normal text
in man pages, and still readable in raw format.
