* tests/pkg/magicchar.tcl:
* tests/autoMkindex.test: Test for fix for bug #2611.
* library/auto.tcl: Fixed the regular expression that performs $
escaping before sourcing a file to index. It was erroneously
adding \ escapes even to $'s that were already escaped,
effectively "un-escaping" those $'s. (bug #2611).
