[PATCH] src/cdda-player.c: always use "%s"-style format for printf()-style functions
`ncuses-6.3` added printf-style function attributes and now makes it easier to catch cases when user input is used in palce of format string when built with CFLAGS=-Werror=format-security:
cdda-player.c:1032:31: error: format not a string literal and no format arguments [-Werror=format-security] 1032 | mvprintw(i_line++, 0, line); | ^~~~
Let's wrap all the missing places with "%s" format.
[PATCH] Use getmntent/setmntent for reading mounts Since fields in the mtab and fstab files are separated by whitespace, octal escapes are used to represent the characters space (\040), tab (\011), newline (\012), and backslash (\\) in those files when they occur in one of the four strings in a mntent structure. The routines addmntent() and getmntent() will convert from string representation to escaped representation and back. When converting from escaped representation, the sequence \134 is also converted to a backslash.
