Hi,
While programming a script I found it useful to have parameter expansion 
replace the last occurrence of a given substring instead of the first 
but fund no way to do it. I hope this is the correct place for feature 
requests since I found no searchable location for them to check if it 
was already there.

The idea would be to have a third option to the already existing two:

|${PARAMETER/PATTERN} # replaces first occurrence|

|${PARAMETER//PATTERN} # replaces all occurrences|

I was thinking about |${PARAMETER/%PATTERN} but that is already taken by 
anchored replacement.

With best regards,
Alan
