Agreed. In theory there might be some point in removing leaks that happen
per-statement, so as to avoid unreasonable memory bloat when processing an
extremely long input file. In practice nobody has complained about that,
and if somebody did I'd probably question the sanity of putting so much
code into one file. (The C compiler would likely bloat even more while
processing the output...) Moreover, given the way the ecpg grammar works,
it'd be really painful to avoid all such leaks, and it might well
introduce bugs not fix them.
In any case, if this TODO item is going to lead to ideas as dubious
as "let's free progname before exiting", it's not helpful.
