--- Comment #2 from Michael V <m.v...@wanadoo.fr> --- To be totally clear. I think there are 2 issues here: 1. The behavior of -K regex. This does work: man -K "BIOS\sextension" this doesn't: man -K "BIOS extension" 2. the fact that '\s' is not documented in man page and contradict re_format man page. -- You are receiving this mail because: You are on the CC list for the bug.
