.. BEGIN SYNOPSIS
.. synopsis::
string trim [-l | --left] [-r | --right] [(-c | --chars) CHARS]
[-q | --quiet] [STRING ...]
.. END SYNOPSIS
.. BEGIN DESCRIPTION
string trim removes leading and trailing whitespace from each STRING. If -l or --left is given, only leading whitespace is removed. If -r or --right is given, only trailing whitespace is trimmed.
The -c or --chars switch causes the set of characters in CHARS to be removed instead of whitespace. This is a set of characters, not a string - if you pass -c foo, it will remove any "f" or "o", not just "foo" as a whole.
Exit status: 0 if at least one character was trimmed, or 1 otherwise.
