Comment(by leif):
What sense does it make to first call `resolvelinks()` and then finally do
{{{
#!sh
SAGE_ROOT=`cd "$SAGE_ROOT" && pwd -P`
}}}
?
Also, why use all of `[ "x$foo" != "x" ]` (causing eye cancer), `[ -n
"$foo" ]` and `[ "$foo" != "" ]`?
For `sage` at least, or any script that's run by `bash`, `[[ -n $foo ]]`
or `[[ $foo != "" ]]` does the job, and is by the way both safer and
faster.
