Suppose I have this:
set text '-foo'
How can I determine whether the first character of the string in $text is a
dash?
I tried this:
set firstChar (string sub -s1 -l1 "$text")
But that doesn't work because "string sub" thinks I'm trying to specify
another switch since $text starts with a dash, and of course "-foo" is not
a valid switch for "string sub".
