Well I think ``SHELL = @config_shell@'' is ugly :-)  Why can't the 
configury code edit ``s/^SHELL =.*/SHELL = $.../''.

The mechanism is very old (it pre-dates me as GDB release engineer). 
Changing it is going to involve updates to many things - snapshot 
scripts, release process doco, .... so won't happen overnight.
