Subject: intro.1, clock_getres.2, clone.2, futex.2, ioctl_fat.2, mkdir.2, mknod.2, mmap.2... 
X-Git-Tag: man-pages-5.08~14
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=af2d18b2c26ede995f8e41c5a8fe3ad6331dce98;p=thirdparty%2Fman-pages.git

intro.1, clock_getres.2, clone.2, futex.2, ioctl_fat.2, mkdir.2, mknod.2, mmap.2, open.2, statx.2, umask.2, userfaultfd.2, glob.3, mkfifo.3, termios.3, wordexp.3, console_codes.4, sk98lin.4, vcs.4, dir_colors.5, hosts.equiv.5, proc.5, termcap.5, utmp.5, ascii.7, bpf-helpers.7, charsets.7, environ.7, glob.7, mailaddr.7, netlink.7, operator.7, suffixes.7, tcp.7, unicode.7, uri.7, zic.8: Use "\(ti" instead of "~"

A naked tilde ("~") renders poorly in PDF. Instead use "\(ti",
which renders better in a PDF, and produces the same glyph
when rendering on a terminal.
