Certainly trying to avoid bash-isms seems like a good idea.
Especially in scripts where it isn't really that hard.
OTOH avoiding posix features (so the script will run on a traditional SYSV
/bin/sh)
is probably excessive.
I'd use "${foo%"${foo#?}"}" to get the first character without bash-isms.
But, IIRC, one version of ash/dash made a 'pig's breakfast' of the nested
pattern match.
(Most syntax highlighters don't get the quoting right either...)
