~~Make sure `LC_ALL=C` is set when using `grep` range expressions.~~
Make sure `LC_ALL=C` is set in all shell scripts.
From the `grep(1)` documentation:
> Within a bracket expression, a range expression consists of two characters separated by a hyphen. It matches any single character that sorts between the two characters, inclusive, using the locale's collating sequence and character set. For example, in the default C locale, `[a-d]` is equivalent to `[abcd]`. Many locales sort characters in dictionary order, and in these locales `[a-d]` is typically not equivalent to `[abcd]`; it might be equivalent to `[aBbCcDd]`, for example. To obtain the traditional interpretation of bracket expressions, you can use the C locale by setting the `LC_ALL` environment variable to the value C.

Shell script cleanups:
* Add required space to `[ -n ]`.
* Avoid quote within quote.
* Exit if `cd` fails.
* Remove `\n` which is not handled by `echo`.
* ~~Remove redundant `$` in arithmetic variable expression.~~
* ~~Use `$(command)` instead of legacy form `` `command` ``.~~
* Arrays are not supported in POSIX `sh`. Use `bash` when arrays are used.
* ~~`[ foo -a bar ]` is not well defined, use `[ foo ] && [ bar ]` instead.~~
* ~~`[ foo -o bar ]` is not well defined, use `[ foo ] || [ bar ]` instead.~~
