base-files: functions.sh: replace [^...] with [!...] in case
Strictly speaking, ash does not support it. From https://wiki.ubuntu.com/DashAsBinSh#A.5B.5E.5D Not to be confused by sed's and other program's regular expression syntax. Uses of [^...] in case (parameter/word expansion in general) need to be replaced with [!...].
