Summary: Un-free'd DString in regc_locale.c

Initial Comment:
The function "cclass" in regc_locale.c
has a Tcl_DString at line ~725 which is not
properly Tcl_DStringFree'd.

A memory leak can be triggered by:

while {1} {

set str 
{a_very_very_long_string_which_is_greater_than_TCL_D
STRING_STATIC_SIZE_characters_long_blahblahblahblahb
lahblahblahblahblahblahblahblahblahblahblahblahblahblahbl
ahblahblahblahblahblahblahblahblahblah}

 catch {
  regexp "a\[\[:$str\:\]\]b" axb
 }
}


Cheers, AJD.

Someone had put Tcl_DStringInit() instead of Tcl_DStringFree()
Fixed in HEAD for 8.5, and I can't be bothered to backport
to 8.4 since this is really unlikely to come up a lot in
production code!
