In gsub, when the destination string is empty, the string 't' is
provided and the regular expression doesn't match, then the final result
is an empty string.
Example:
=> echo ${foo}
=> setenv foo
=> setexpr foo gsub e a bar
=> echo ${foo}
=>
The variable ${foo} should contain "bar" and the lack of match shouldn't
be considered an error.
This patch fixes the erroneous behavior by removing the return
statement and breaking out of the loop in case of lack of match.
Also add a test for the no match case.
